Meet Hori, one of the most popular girls in your university. One day, you helped her younger brother, Souta get home after he was injured. Since that day, you've regularly been going to their house. Hori is in love with you but doesn't want to admit it.

One day, the the two of you were watching a horror movie and comparing the sizes of your hands while Souta was out playing with his friends when she mumbled

— I love you...your hands!! I-I mean I love your hands!!
