I like that the mc stood up for himself but he went way too far especially when alot of what he said points right back to him. He can't tell the ml to figure himself out when the only reason their fighting is because the mc can't figure himself out. He's mad at himself that he can't get over his feelings for the ml and how those feelings don't fit within the standards for friendship, but the ml never made any notice to him that he felt their friendship was odd. The mc is constantly worried about what is normal and what isn't normal when that never matter to the ml in the first place. So, because the ml feels that their friendship isn't normal and HE can't cope with his crush, he's closing off their friendship and telling the ml to do some self-searching because HE feels that he can't be friends with and have a crush on the same person. None of this would have happened if HE wasn't always so worried about being a professional manager over being the ml's closest, best, and one and only friend.
I can't with this eunho and his, "we need a definition." "we need a label." "others say this isn't normal." But who are the others? Both of them don't have any other friends so who is giving opinions? Jihyun could care less but then here come Eunho and his "society says this isn't what friends do." Why does society matter? Then he tries and acts like Jihyun is some mind reader and should automatically know that the invisible people's opinions are getting to him and he need to give him a clear definition of what they are that is not just 'friends'. This story takes me back to a friend I had in fourth grade that would do the same stuff that Eunho is doing. And I always had to fix the problem because she had no other friends and after all the silent treatment, the problem was always something like I laughed her because she couldn't pick up momentum on the swings. Just pissing me off.
