At 1st i hate the sis, bcs this type of sis truly just unimportant side chara to make seme n uke met nothingf more.but it changed bcs his lovingness n smartness to reach their target together with uke. Yeah to rebuild their company, sis need to make revenge to seme by blackmailing him.but it replaced with useless uke, uke did a good job to arrange the date or flirt seme while sis is sick.but seme knows evevrything so he play along.
But the minus point is about split personality who isn't match
