Elektel Delusion
Shunpei and Fumi are best friends and neighbours. One day, Fumi tells Shunpei he might be gay and has agreed to go out with another guy in school. Shocked at this sudden confession (but very accepting), Shunpei questions Fumi about all sorts of things regarding his newly-discovered homosexuality - subtly aware that he's disappointed that Fumi picked someone else over him - and, upon meeting the boyfriend, cannot take that Fumi chose someone who was more or less normal... like Shunpei! NOTE: Chapter 5 and 6 of volume 1 are extras of Otona Keikenchi
Heart no Kakurega
Robbed nearly blind, Izumi is forced to move out of his apartment into more housings, which means shacking up in a run-down tenement complex with five quirky neighbors, including Haruto, the weirdest, most seemingly unsociable landlord he's ever met. Izumi is convinced all he has to do is buckle down at work and put up with this miserable situation for the time being until he saves up enough to move, but then, they all kind of start to grow on him, especially (and perhaps most unexpectedly) Haruto!
