I'm sure someone will offer a clearer explanation but from what I understood, he helped in spreading the video of the other guy. He knew it was wrong though so he felt somewhat guilty. That's why he was so frantic when warning Sun Hwa about involving himself with the black haired dude (forgive me, I am not the best at remembering names), because he knew the potential risk of exposure it could put Sun Hwa in. It is revealed that he is still guilty of his actions in the present but I guess he just never gets around to admitting to his role in spreading the video.
He actually did admit to it. The second time they met (without the MC's ex), his friend explained his role in the situation.
Oooohh,, yes I remember now thank you
No Problem :)
It's just me or everything is just so confusing?
What did MC's friend do?
I understood that he took some kind of video? (With the sunbae and his previous BF?) What is his role in the story??
And why is given so much importance to flashbacks and there is just a small part of character development in the present?
It's so sad because this could have been a beautiful story but in the end I'm just really perplexed. °^°
