For his 16th birthday, his father gives Keito a surprising present: an elder "brother"! Code-named K-5, this "brother" is a robot whose only function and order is to love Keito.

The third chapter's a oneshot on a girl who puts on a smiling, obliging smile of a mask no matter what her classmates demand from her.
