Chotto Matte yo Hanaya-san
Florist fell in love with optimistic University guy who has misfortunes
Soredemo, Yasashii Koi o Suru
Older uke fell in love first with a straight seme who's completely oblivious to love. Kept his feelings secret until seme confessed that he fell in love (and got dumped immediately) by a male colleague. Uke decided that maybe he has a chance, but then a whole bunch of misunderstandings happen. Ended up together after all, and Seme is crazy in love with finding out how cute his older lover is.

Kiss Mo Dekinakatta
This is the spin-off couple for the second love interest. I love the "replacement lover" trope when it ends well. It's a good type of heart-wrench “Mikazuchi Dorm” a dorm where the male students live.Sagara never had a problem finding a partner, but for the first time had his heart broken. As it was hard for him to stay at the dorms, he ventures to his childhood friend, Hibiki’s Dorm instead. But as Sagara realized Hibiki looked like the vice dorm leader when he wears his glasses, he asked him to “comfort me” as a joke. To his surprise, Hibiki agrees. Drunk in Hibiki’s erotic expressions, they have sex. After, Hibiki actually confesses to him, saying he's always loved him…!? Arrogant hottie x Courageous man, a love that stemmed from being a replacement. The third story of the Mikazuchi dorms
