Words can't fully express just how meaningful and beautiful this manga is.
I searched it up, and yellow forsythias mean anticipation, renewal, hope, and arriving of spring.
It perfectly symbolizes Seong-ah's feelings for Jeonsu.
Seong-ah has anticipated things with Jeonsu that makes him question himself because he rarely expects anything. The words renewal and hope hits hard because it completely expresses the change in his life. Seong-ah saw Jeonsu as his light, and his renewed life started after he found Jeonsu again.

Five stars isn't enough to express how much of a good story it is. It's absolutely a nice read. The yearning is just chef's kiss. The censorship is a bit frustrating tbh.
