Ai to Yobu ni wa Mada Aoi

The extraordinarily normal salaryman, Sawatari Takumi, has the same old conversation with his friend, Inubushi Motoki, on the way home from work. At least, that’s how it’s supposed to be, but he’s suddenly kissed! “I’ve always thought you were cute.” Takumi, unable to hide the shock and confusion he feels about his friend’s sudden coming out, rejects Motoki with thoughtless, harsh words. Though he thought their relationship would end with that, things take an unexpected turn...! Thus starts a painfully sweet adolescence for these adults.
