Hananoi-kun to Koi no Yamai

Sixteen-year-old Hotaru Hinase understands the value of family and friendship, but romantic love has always felt like a mystery she can live without. After witnessing handsome schoolmate Hananoi go through a harsh breakup, she later finds him alone in the snow and casually shares her umbrella with him.

The next day, Hananoi asks her to be his girlfriend. Hotaru refuses at first, but he suggests they spend time together and let her discover who he really is. She eventually agrees to try dating in hopes of learning what being in love actually means. Hananoi's intense devotion can be deeply kind, but it also carries a weight that both of them must learn how to understand.
