I'm Frustrated! Episode 6

Takeya stops Ren from sexually advancing, calling it too soon. Slightly awkward from this, he distances himself from her for most of the day. Miu invites herself to reform Ren by showing her to cook and gaily decorating the apartment. As Takeya throws out the flashy new room additions, he is hastily tackled by his stepsister, Natsuki Ikuhara.
