It's been two years since Kenji confessed his feelings to Tomo before returning to the city, and now Tomo decides to surprise him by visiting him a day early, just before Christmas. Upon arriving at his flat, however, she's greeted by a familiar looking girl who claims to be his "new girlfriend". Just what's going on?
Note: Although this was supposed to be the final chapter to this series, Ichinomiya Yuu is planning to release a follow-up "after story" as two separate works some time after the next comic market. The two stories will feature separate NTR and pure love endings.
Keep at it.
