Melancholic Trickster
Very cute and sexy story about an idiotic host who reunites with someone he has forgotten from his past. Although the tag reads that the manga is incomplete, it works as a short 2-chapter story.
Twin's Labyrinth
(1) Rin, owner of a host club, mistakes Ayamu as a potential suicide and brings him home to work as a housekeeper in exchange for free rent. Lack of communication leads to misunderstandings when Rin's twin brother and host, Ren, shows up and develops a liking for Ayamu. (2) After Ayamu rejects his advances, Ren decides to console himself with the newest host club member, Shion, only to discover that he has an irrational fear and hatred of men. When a belligerent former associate of Shion's appears, it becomes apparent that Shion's fear and hatred aren't so irrational. (3) Forgettable story about jealousy and meet-ups. (4) Cute story about the Goth clothing fetish.
Koishite Hoshii
Childhood friends: one's a doctor, the other's a host who visits him to get his booboos patched up. On one such occasion, the doctor casually mentions he has a girlfriend which sends the host off in a fit and the result is a formulaic romance story trope.
Futsuriai na Chocolate
Oosawa, host club manager, tries to flirts with Fukagawa, uninterested librarian, but the barriers are high and solid. He perseveres, but after an entire chapter, there isn't so much as a nibble. Will Oosawa's glue-like persistance pay off? Since the manga isn't labeled yaoi, it's anyone's guess.
