@namjoobs Oh you're right. It's actually "On my Own"
Okay, Id like to ask another bl. This one is bothering me so much and I read this too in Mangaowl.
So the story starts when highschool boys kissed each other in the school. But there's a problem, a pictures was taken when they are kissing. Well, the mc's face isn't really shown on it, but the seme's face is. So, the seme kinda(?) got bullied for it and he moves to different place. So this is where the story begins, after many years, the mc got a gift from the seme. And it is a book. That book's main character is the uke and it have a bad ending. So, while reading it, the mc got inside of the book and do not mnow on how to get out. It's setting is from the past, I think Joseon(not sure on what period it is, but it's in the past).
In that era, he met someone who have the same face as that seme in modern era. Like the one he kissed when he was in highschool. But this guy is different since he kinda have a dark aura in him and he also hated the uke.
So yeah, that's the only thing I remember, but I hope you can help me find it.
