Clearly, you don't understand the Uke's character. You can tell that he's actually a genuine person but he wouldn't just put his guards down especially in their life situation. And of course to all he have been through do you want him to act normal? He had an amnesia and all, of course he isn't stupid. after realizing and remembered that the Seme is been helping him all along you can see him being genuine towards the seme.
people just have a PRIDEFUL personality. And thats the Uke's character. You can also see him that he always give the seme all he wants like having a rounds of sex and even giving a chance for the seme to come with him, he even got back to the building to save/help the seme. And he didn't he says that he's GREATFUL?
ugh, i hate a bratty bottom that’s bratty for the sake of being bratty, especially when the seme is kind & respectful. the story was cute, i love the disability representation, & jihoon was such a gem.
