Azuki-chan is a manga series that chronicles the tale of Azusa Noyama, a student who was mistakenly referred to as Azuki when she was younger, leading to her nickname. At first, she loathed the moniker, but her feelings changed after she encountered a new classmate named Yuunosuke Ogasawara who made an effort to remember her name, becoming the first person to give her recognition. This occurrence triggered a newfound fondness for her nickname as well as for Yuunosuke. However, Azuki finds herself feeling jealous whenever she sees Yuunosuke interact with other girls, unable to understand why he is unaware of her feelings.
