Bokura No Negai
Multipairing (Step-brother/Step-brother, Younger seme/Older Uke) story that is linked to another story about two characters in a flower shop (Older boss seme/Younger employee uke). There are ups and downs and genuine self conflict on sexuality and family, as well as the weight of fears and responsibility as an adult to a younger person.
Koi to wa Baka de Aru Koto da
Ogeretsu Tanaka is a recent high-ranker in my personal list of favourite BL mangakas. Her stories are incredibly amusing, heartfelt, and unique. Stories vary, though one contains dub-con.
Escape Journey
What I love the most is the real issue of conflict here. Sexuality, relationships, self-esteem, trust, and communication. All delivered beautifully Ogeretsu Tanaka's art and story-telling. It starts bittersweet, and ends up as box of multicoloured macaroons.
Junjou Romantica
Been obsessed with this for 6 years to the point that I traveled to Japan to visit its anime event cafe. Favorite pairing is Egoist.
