One Dirty Butler - S1.E12

Shinra is troubled because her mentor said her performance wasn't as good as her earlier work, so Ren decides to ask Shinra out on a nice date (Colonel even makes sure Ren wins Shinra a panda by disguising himself as the custodian) but Shinra gets angry at Ren because he says he understands her feelings and asks Colonel to drive her to the rehearsal. On the way home Ren sees his father whom he gets angry at after his father says it was his fault Ren's mother died by giving birth to him (not literally). The two prepare to fight.
