Mr. 100% Perfect
Main couple had broken up, but meet again while uke is on a new job as a house cleaner. Seme hasn't recovered from their breakup (his obsession with putting up a fascade to be the perfect person for everyone eventually caused this breakup and for him to break down) and seeing this new/vulnerable side to him makes the uke willing to give him another chance. The Seme's brother finds out and due to their spiteful past he tries to ruin the main couple's relationship, but promptly turns his attention/affections towards the uke's coworker. A man he had met months prior on the roof top while stepping away from his birthday party (the coworker had contemplated jumping after naively being scammed, but didn't due to the other man arriving). + A good story where you end up rooting for the success of both couples.

"A 4koma gag series that transforms into a slice of life school comedy about 5 junior high school boys & their guardians, mixed with some shady mafia mystery". + Really good & funny fr.
