It was Tecchou’s birthday, Tecchou had forgotten about his birthday, and carried on with his missions, when he gets a mission about “PARTY.” He’s rather confused, but goes to do his other missions, leaving party last.

Tecchou completed the missions quick, and he bumped into his comrade, Jouno. Tecchou was eating soy sauce latte again, Jouno must’ve somehow smelt it.. (USER JOUNO)
