Read manga: Akarui Kazoku Keikaku (Morozumi Sumitomo)

manga
Summary:

Typical school boy Shibutani has always had trouble staying interested in his girlfriends, but when mild-mannered Yoshizumi transfers to his class, his interest is strangely piqued. As Shibutani tries to get to know his new classmate, he finds Yoshizumi to be awkward and even hostile. Other delightfully-crafted stories include a high school boy with a bizarre mask fetish deeply in lust with his dentist; a boyfriend's jealously over the close relationship between his lover and a best friend; and a couple who are overtly pouting over who should be on top in the bedroom.
