Doesn't seem to be the case. He spends the night having nightmares about his past life with his ex. Wakes up to see DG in his house, reflects on what happened in the hallway etc, DG is trying to make small talk and avoid what the situation is, whereas Jiwon just cuts to the chase, and asks DG if he in love with him, to which DG eventually replies yes.

Chapter 35 is out on the Korean Lezhin. https://www.lezhin.com/ko/comic/bjalex

I posted this google translation of the flashback scene earlier
- Jiwon) I'm home
- Jiwon)..... ?
- Brother) Oh you're back. I'm going out now.
- Brother) Ah! Say hello
- Brother) This is my friend xxxx (the name is deliberately blurred)
- Jiwon's thoughts) I still regret it. If I could revisit that day, I never would have looked at him. I was young and foolish that day.
- Jiwon) I love you. I love you (to his ex in bed)
- Jiwon's thoughts after seeing his ex cheat) How can this be!
- Jiwon to his ex) How! How long.... How long hyung... Was it a lie, that you loved me...?
- Ex) You loser. Did you believe that? Were you that naive?!
- Jiwon) Don't laugh. Don't laugh!!!!!
The next scene with DG isn't as clear in google, but Jiwon basically says great it's only a dream, why does he still have to remember his ex. That his head hurts, and he remembers having to drink with his professor. He sees DG asleep on his couch, them has flashbacks to everything that happened. DG says something like hello Sunbae, you weren't well so I was waiting here until you were okay or something. Then starts to make some small talk about exams, as he too is remembering all that happened earlier. Jiwon has a flashback to his ex's face and is motivated to have courage to just ask DG straight "I was wondering if you love me" DG gets flustered, so Jiwon asks him again, and DG says yes.
i bet in the morning he is going to regret it ╥﹏╥
