Cousin needs to just leave... They didn't get together before and they aren't ging to now, so why in the hell does he have to be a winy little shit..... And Lin(?) needs to use his brain and realize hes in love with his best friend and do something about it and tell his cousin to f-off.
The reason the male lead can't easily discard the cousin is because the cousin playing a cliché character role that is super common in Chinese online fiction: the "white moonlight" love rival, aka the male lead's old flame that still has a hold on him because he couldn't stay with them, and thus became unable to forget them, over-idealizing them. In Chinese novels, any male lead that has a "white moonlight baggage" in his past usually needs to get over it first, along with his unrealistic, excessive idealization of the white moonlight, in order to start prioritizing the relationship he has with the mc. Think of the typical "white moonlight" character as the still-alive, Chinese variant of the Lost Lenore ( https://tvtropes.org/pmwiki/pmwiki.php/Main/TheLostLenore) in which the Lenore is still alive and playing a love rival role because "distance made the (male head's) heart grow (obsessively) fonder"...

Ren's teacher thinks that it's Ren fault that his brother died cos his brother went to help Ren when he was little? So he is going to do something to Ren and Haru, cos hes a Dick... or am I misunderstanding something.... it's kind of hard to remember everything since it takes forever to get updates on this.









I really hope there is a point to this, cos right now it makes no sense as to why he is laying in a coma but his mind is in the past... We need to know about all that happened way back then for what reason? It has nothing to do with what is going on.
