the last part of dongchae's suicide note.
"p.s. those bullies found out about eunchae. please protect my sister. i'm sorry for being foolish until the end."
the parallel between hamin's flower, gaeul's flower, and dongchae's flower.
dongchae who wanted to hold hamin's hand during that rainy day. jaemin and subin who wanted to save dongchae, as much as they wanted to save (but they couldnt) their beloved ones in the past
dongchae: i heard that kids who were born in the winter are resistant to the cold. but bc thats not the case for me, ive always waited for the spring. but my winter is too long and cold (...) i'm going to end this cold season that feels like it'll last forever
"ive been bullied for quite a long time. it was started with my old friend's betrayal but i have no intention to blame him (...) and also, i know the perpetrators who are more awful than him as well as bystanders who are sometimes scarier than the perpetrators."
subin going outside to get some fresh air after looking at gaeul's kkt profile and then he met somang who's looking for dongchae. subin said he saw dongchae earlier and clearly remembered him because his expression looked very desperate.
