「お願いしちゃう？」 (Onegai Shichau?)
Episode at a Glance:
On New Years, Kouta is relaxing at home when Chizuru comes crashing in through the door to spend some time as lovers. While Kouta tries to spend the day normally by doing some kakizome (書き初め), i.e. “New Years writing”, Chizuru’s boredom leads to her taking advantage of Kouta as usual.
