Darling Only You! Yuzuki is a girl with a problem: she has a brother complex and can’t seem to get over the fact that her sibling, Kouta, is now dating someone. Soon after discovering the news, she runs into Atsushi-kun, a boy from a different school who has an uncanny resemblance to Kouta. Positive that their encounter must be fate, Yuzuki tries her hardest to get closer to Atsushi, but doing so might be difficult as he wants nothing to do with her!
