Ren'ai Shinan!
I really liked all of the couples. The first couple were Hatano who helps his boss, Honjou become popular by helping him to change his looks. However, he becomes too popular which kinda of upsets Hatano who never wanted a serious relationship until now. The second couple is with Kiriya and Hirua who work together. Kiriya is kinda of quiet and Hiyra is too easy going and popular. However, one day on the bus Kiriya gets accused of molesting some girl so Hiura protects him by saying they are lovers and kisses him. After they do they start a relationship. The last couple is with a struggling kid who wants to go to art school and the guy who hires him to be a model, which turns out to be the artist he admires.
