i dont think jae yeol even likes hyung suk romantically,,, just an admiration n as for him getting jealous of his sister? thats his sister, ud be a little concerned if your sister was all up on your friend. i think jae yeol just really cares for hyung suk. and hyung suk just sees him as a close and caring friend.







this manga reminds me of that anime/manga Erased, it was popular back in 2016 and it was one of the best anime i have ever watched I would recommend it if you found the time and changing fate aspect of this manga really good
You're right it is similar. But regarding Erased, I read the ending. The anime's ending felt so short.
