Keep Holding On 

8 years is a long time to have a crush. Doubly so if that crush is your own best friend. Han-gyeol is tired of his own heartsickness for his childhood friend Sooho, and he thinks that maybe it's about time for him to let go of these feelings. He's contemplating moving on, but there's something inside of him that can't help but cling to this crush. Will there be a reward waiting for Han-gyeol if he keeps holding on, or will it only end in heartbreak? (Source: Lezhin US) Note: Includes three extra chapters.
