Cherry Blossoms After Winter, 1

Haebom is orphaned after his parents are in a tragic accident and is taken in by his mother's best friend and her son, Taesung. In his new home, he tries to keep a low profile to avoid causing trouble, but over time, Taesung becomes distant, and years later, they barely speak. However, in their senior year of high school, something changes when Taesung intervenes to defend him from a bullying incident. Could this be the opportunity Haebom has been waiting for to rekindle their relationship?
