Love at Least

Yasuko is a hikikomori and has hypersomnia (trouble staying awake during the day). She lives with her boyfriend Tsunagi, who works in the editorial department at a magazine. Her frustration grows because she can't control her emotions, and her boyfriend seems indifferent to her. One day, Tsunagi's ex-girlfriend Ando appears. She schemes to break up the couple.
