He could just. .. Leave the MC alone for that ╮(￣▽￣)╭ he LIFES IN HIS FUCKING HOUSE.
No, we get that. What we hate tho is the absolute assholery of Taehoo or whatever his name is （￣へ￣） He could behave differently, even treat him nice as a friend, if the love has to mutual (and verbally acknowledged as one) for mermaid to die. But no, he decided to behave like a pinnacle of douchery instead...
I think you all are missing a point here the seme says all those things so that the uke doesn't realize that he is love by the seme and that he doesn't fall deeper in love with the seme and he doesn't die....... So basically the seme is doing all of this to keep the uke alive
