—SPOILER——-
From what I remembered from the novel, he acted weird on their way back NOT because he wants to confirm if he can get it up knowing he’s a guy or something, but because he was having turmoils if Hakyung would like him cause HE is a guy.
Yoonsung like Hakyung (whether he’s a guy or girl), he really doesnt care. He just likes Hakyung and he is confident that Hakyung will eventually like him as long as he pursues him. However, he thought that maybe because Hakyung is a guy, he doesnt have a chance to him (in short, what if Hakyung is straight and he can’t consider Yoonsung as a romantic partner)
This is one of the beautiful parts for me in the novel. When he found out, he was angry not because Hakyung is a guy but because he thinks that Hakyung will not like him
Uhh so is chap 31 the time when Yoonsung found out Hakyung is a guy? That’s why he kissed him cuz he wanted to find out if he can get it up knowing he’s a guy?? I really want to know now
