Koi Nanka Shitakunai
New to a blended family, affectionate younger stepbrother, Yuuto, falls for his sophisticated gay older stepbrother, Ryuusei, and does his best to repress his feelings for the sake of their family. The plot revolves mainly around misunderstandings and communication failure, but it's a good story and plausible given the ages of the two main characters.
Colorful Line
College student, Shousuke, comforts his childhood friend, Tomoki, every time he gets dumped by a new girlfriend. Tomoki never realizes that Shousuke is suppressing his true feelings for the sake of their friendship. This is the story of what happens when these feelings build up too much. Ichikawa Kei's art has a rough beauty which makes these characters and this story quite charming. The first chapter "The Day They Became Lovers" is hilarious, or would be if it weren't also touching and real in a slightly overblown way.
Tomodachi Ijou no Koto, Shitai.
