The girls welcome the new year and Adachi seems to be acting weird again. She later tries to ask Shimamura if she'd want to hang out on Valentine's Day.

Adachi tries to figure out what kind of chocolate to give to Shimamura. Later on, the girls go to Nagafuji's house to play a game.

Valentine's Day finally arrives and Adachi and Shimamura hang out as promised. But this time, it's actually Shimamura that has a surprise in store for Adachi.
