So I searched for this webtoon on Naver and found it had 2 chapters so far. With my broken Korean, this was what happened next:

Some girls invite fem lead and the short hair friend to a cafe. One girl confesses she likes the popular guy and asks if FL likes him, which annoys FL's friend. So the friend takes this chance to announce she likes him too, which surprises FL. And as FL doesn't want to be on bad term with her friends, she lies that she is in love with the gloomy guy in their class (male lead). At that moment, ML is sitting at the table next to hers in the cafe so he and his friends hear everything loud and clear. Thus I think they fake their dating as shown in future scenes. Not sure if ML has anything going on with FL at this point though.
Base on chapter 1, it seems FL has a light crush on the popular guy but steps back for her friend's sake. And the one that guy likes is probably the friend because it's common in shoujo that the boys will tease whom they like a lot. This is just my guess, since there're only 2 chapters now. Waiting for more (๑•ㅂ•)و✧

Mashuu is a sensitive child. He's more mature and tends to think differently than other kids, so his romance can't be just anyone around his age. He might think of Satoko as an older friend or practically a substitute for his mother at first, but it changed as he grew up. It's okay for Mashuu to be a bit vague about his feeling toward Satoko. Even if they can't be together at the end, I believe Satoko will always be important to him. It's Satoko I'm worried about. She also thinks a lot and is too cautious of prejudices about normal relationship. It'll be hard for her to open up to anyone after Mashuu

I hate ML already. By the way, there was someone in the comment section didn't like it when others criticized ML and kept replying in a rude way. It's very childish. Everyone has their own opinion, he or she needs to calm down and accept it

I'm going to be honest with you, I haven't seen anything that would result in me hating Kiyu. Yes, he judges people off his appearance (and it's infuriating, trust me), but almost everyone judges people off of looks (and rumors) until the get to know the person (Hell, even he was judged based off his appearance and I'm assuming it got too overwhelming for him and that's why he left the agency. Which is why he wears glasses). Also, you got to remember he's just a teenager, and teenagers are still in the process of learning. Luckily, even though be learned his lesson he's still scared of Baek because she always has this scary look on her face, so we really can't blame him or anyone else for being scared.
But if that's not why you hate Kiyu, then please tell me why. I can't help, but think it's because of his judgment since everyone is talking about that.
I've been super happy lately because my favorite manga is updated so fast. Thank you so much Daphie and Nakain. You are really awesome! ε=ε=(ノ≧∇≦)ノ
