Seol is thinking on how to make excuse to Sangcheol, Jung came and asks them about what they were talking about. Sangcheol asks about Jung's watch and the price is a couple of thousand dollars. Euntaek says he also has watch like that from his relative, he is playing basketball. Bora tells Seol that there are something about Euntaek and Younggon. Younggon is really a stalker.
Seol tells the assistant and the assistant calls the professor. Assistant tells that the professor says he'd take her assignment on monday, Seol complains how can she finish it within 3 days and the assistant says that is her problem. Jung appears and says sorry that he was busy and Juyeon made mistake, he asks her if she needs his help but someone needs Jung to translate. Seol says that she isn't interested in Jung ans she quit already but Juyeon starts cornering Seol, Jung suddenly appears with his friends and Juyeon wants to join him but he offers help to Seol. Back to present, Jung is in front of Seol and they are working for their assignment, he will take care for the rest. Jung bring convenient store foods and did a good job on peeling the triangle food this time. They were laughing together and when Jung looking at the wind, Seol feels like she is like falling for him, Sangcheol suddenly appears and Jung picking up his phone. Jung asks the person on the phone how is his/her feeling, that person asks him to come and Jung agree and asks Seol to stay there. Sangcheol asks Seol about Ayoung's number again.
The girls and Euntaek eating cake for the birthday party, the girls starts to gossiping about Sangcheol to Younggon. Jung messages Seol about assignment that they're supposed to do together. Flashback, Bora and friend tells Seol to eat but she wanna write a note before she forgets, her handwriting looks so bad and Juyeon gives her a paper for assignment, Juyeon cornering her about Jung and study group, Juyeon and Younggon start bickering, Seol runaway but Younggon follows her. Younggon says he will embarass Juyeon so Seol should set him up with Bora, he says he was taking her side earlier and thought they were on the same page, he could also help Seol with Jung. In the class Seol warns Bora about Younggon, and they noticed the paper Juyeon gave to Seol is wrong and different from Bora's. Something small and so trivial to worry about could become big like firestorm.
Seol's morning and then in the class Bora and Euntaek talk with Jung, Jung is borrowing Seol's pen in that class. After class, Ayoung waited for Seol and Seol warns her about Sangcheol. Jung returns the pen to Seol and Seol exchanges thank you with Jung. Ayoung fell for Jung. Ayoung and Seol eating dinner together and Ayoung tells her that Sangcheol approached her. Ayoung asks Seol about Jung.
Seol, Bora and Euntaek buying cookies in supermarket to bring, the other group bouth the cake. They are getting something for karaoke. Bora asks Seol if she wants to go to blind date, Bora went to blind date the other day. Euntaek is trying to reach for something in the back, but everything fell. Euntaek got many things and Bora tells him to put them back.
Seol went to toilet. Jung looks at his watch and asks for them to take a 5 minute break. When the time to go home, Seol almost fell and Jung catches her. Seol felt something wrong. Seol wake up after dreaming in the class, the students laugh at her, Jung says Seol looks tired and he doesn't waking her up because she was sleeping like rock, he has got her handout and giving it to her. Jung and Seol walking together, Jung asks her if she wants something to eat, Seol says she need to clean her house cause her mom will disappointed if she hasn't and will cause her mental distress and ear ache, Jung understands. Shoes, bag, jacket, computer, she doesn't have any other classes she could change to, everytime she sees him she do crazy things, Seol is screaming because stress and the guy next door yells at her.
Seol feels awkward in the group and thinks she came to the wrong place. Younggon complained about the atmospher. Jung says Kyunghwan asks him first and he is gonna say no to Juyeon. Jaewoo takes the role of leader and asks Younggon to be quiet and tell his members to briefly make plans, their schedule fits well and asks them to meet one time during the week and one time during the weekend. Jaewoo advises his member to take 100 words test each time, it means that 200 words each week. Jung tells Younggon that assistant said if he doesn't go to empty his cabinet now, he'll throw everything away. Younggon going and asks them to give information later. Strange and uncomfortable vibe, some kind of sensitive power struggle, it's Jaewoo's group but he can't lead the way he wants to, there's someone with more charisma and confidence, some people just follow the easy path or play politics to gain power and there's someone who looks humble but at the top of social ladder. Jung tells Kyunghwan to stop joking around and check the materials to study. Seol assumed for Jung, some people aren't cool to hang out with, but they are older or high class, some people are jusr easy for Jung to handle, Jung just avoids some people that Seol also finds awful but still everyone approaches him respectfully. Prince or mysophobia? Seol laughs while glance at him and Jung glanced back at her.
Bora asks Seol if she wants to join a study group, Seol asking if it for English. Bora saw the bulletin board and Juyeon advertising for a study group, she said she could make Jung join and help them to practice their speaking. Bora tells Seol to think of her TOEFL score. Seol thinking of try to get close to Juyeon, there'll be lots of girl in study group and hanging out all together. Juyeon says that even if Jung come he might not be able to help Bora and Seol to study and Bora says it's okay because they will just sit there and listen to him. Younggon hitting on Bora and Bora asks him to get away. Younggon asks them to join his study group and they refused. Bora says that Younggon been acting weird to her lately and he was tried that with Juyeon before, so Juyeon made him super embarassed but he won't change and warns Bora to be careful. Seol moves to Jaewoo's group to avoid Jung, Jaewoon is the guy who very quiet and smart.
Seol is late, she ran and fell, Younggon laughed at her and asks about Bora. Floor is very slippery because it's been waxed. There were Jung in the group.
Seol is yawning and thinking of changing her 1 class to online class. Her neighbor calls her and complains to her that she is so noisy and talk so loud on the phone. He studies for the exam and can't focus studying. Sangcheol greets Seol when she waits for Ayoung who just entered the school. Seol wants to take Ayoung to lunch but she has to go to class, Sangcheol joins her conversation with Ayoung and she introduces them Ayoung says that she has to go and left. Sangcheol asks Seol to set him up with Ayoung but Seol lies and says that Ayoung has boyfriend, Sangcheol keep insisting but Seol has class and has to go but Sangcheol says that he was nice to Seol and Seol is so mean, Seol says that she will try but don't expect anything. Seol thinks that she is out of her mind because Sangcheol is not a good person and wrong in many ways. Ayoung helped Seol so many time when she kicked out, lost her lunch money, umbrella, cookies. Jung says that he will study together with Seol, there are not many classes he can take and he choose that class because there seems to be less homework and less people than other classes, Seol answers him that they met there by accident. Seol glances around and says that she will change to online class when she get home but Jung says that lots of online classes have been cancelled, most of the ones left have probably filled up and asks her if he makes her uncomfortable. The teacher calls them and says that she understands romance but they have to listen to the lecture and asks Jung if he is a tv star or something because she feels like she have seen him on shows. Jung says that he is just a student and the teacher keeps compliment his face and tells Jung and Seol to go on a date after class. Students talking that she isn't his girlfriend and guess she's desperate for him and the other sure that she is just his friends. Jung says sorry and tells her to not feel uncomfortable, there is no reason to feel awkward with him and just relax. Seol isn't sure if he means it or just saying it. She doesn't know he just changed his attitude, he used to be a totally different person. He wasn't as simple as that. Flashback again, Seol was yawning, her mouth looks like it's going to rip. She almost stayed all night because of an assignment and she lives too far away, it takes 2 hours just to commute she wish she could sleep, her friend ask about moving and she said that she want to. At that time, she knew he was full of himself at that moment.
A piece of cheese not tasty and not nutrious, Bora says that Seol should eat something she hasn't had before since Jung gonna buy dinner for Seol again. Euntaek says to asks Jung to Paris and buy escargot for her, Jung's family has a jet, Euntaek says of course it's not true.
Seol's perfect morning and in the class Sangcheol was babbling about Seol and Jung study together. And then there is Jaewoo's inferiority complex of Jung and Sangcheol noticing Jung is smiling when people talk bad about Jaewoo. And then there is a construction worker and his conversation with Inho who wears a cap
