Castle Mango Series by Muku Ogura, Narise Konohara

Yorozu lives at Castle Mango, a "love hotel" where couples pay for a few hours to themselves. But his quiet life is violated when Togame arrives to shoot an adult film! Soon Yorozu's being "mistaken" for an actor, having his pants suddenly removed and watching his little brother get hit on. Togame eventually agrees to stay away from Yorozu's brother, but there's a catch - and it's not something Yorozu's going to like!

Ever since he spotted Yorozu with a girl at the fireworks display, Togame has put distance between Yorozu and himself. Yorozu is already anxious because of Togame’s abrupt curtness when his mother suddenly collapses. Yorozu secretly manages the love hotel, worried about his family’s finances. And as if that wasn't enough... his precious hotel burns down?! It’s the moving conclusion to the story of two reluctant lovers who won't face their feelings for each other.
