uke is smart and is unapproachable due to a trauma. his parents died and no one wanted to take him in and he started to be cold to people and became independent. he thinks that he doesn't need friends or acquaintance because he thinks that it is unnecessary. seme is his university acquaintance and seme has always been trying to get closer to him but uke distance himself from anyone possible. until uke faces trouble from being kidnapped by his distant relative's son (who also caused his trauma) for revenge and to be an experiment material for sex dolls. seme, who risked his life to save him and stayed by his side, made uke soft for him and open up to him.
