Riman Love Ho Danshikai
Straight guy Mamori Sendachi gets invited to a "Love Hotel Guys' Night" by his cool co-worker Taichi Ushirogi, but he's a little hesitant. Even so, he still goes with him.
Eat, drink, hang out, and take a bath in the huge tub when you're tired... it looks like Mamori has discovered a whole new way to have fun! But now that he's defenseless, there's a bit more to it -- Taichi has feelings for him!
Mamori notices something is a little off with Taichi... has he noticed how his coworker feels about him?
Their time at the love hotel is a little awkward, but their relationship starts to deepen...
