"The reason I'm here right now is thanks to Ryuu." Ryuu, with a complex about his looks, lives unable to stand up to his classmates who pick on him. One day, his classmate who's as beautiful as a celebrity, Fukuda Ema, calls out to him. Ryuu rejects him saying "we're from two different worlds," but they were actually childhood friends back in first grade. Ema, who used to be insecure about his looks just like Ryuu, has grown not just physically but mentally, says it's all thanks to Ryuu and quickly starts to close the distance between them... Super beautiful popular boy × kind-hearted insecure boy glow-up love!
