Really interesting story. The seme has to prove their love to the uke for a long time because the uke has been hurt before. The uke ultimately falls after a while and they are so cute. The seme is a douche at first but then turns out to be hella loyal asf. Has an additional story, its cute. May small trigger warning for a small scene, nothing too major though.
