彼氏年下系。

Ai reunites with her childhood friend Sou, who returns from America after five years. She is delighted to see that he has grown into an angelic-looking young man. However, their reunion takes an unexpected turn when Sou, who is three years younger, suddenly declares his intention to make Ai his and forcefully kisses her.

Ai has always seen Sou as a younger brother, so his aggressive advance leaves her shocked and confused. As Sou persists in his pursuit, Ai must navigate her changing feelings and the new dynamic between them, questioning whether she can see him as more than just a childhood friend.
