Endings that make me depressed

This was a damn rollercoaster. It’s not your ordinary zombie apocalypse and the author pretty much researched stuff to make this whole story. It has so much angst and drama and I guess a happy-ish ending but not everything was explained at the end. Still good but I would stick to reading and completing it once so my heart doesn’t hurt again.

Man what in the world
The ending leaves so much hanging and I wish the bob cut girl and her brother get hit by a car or something tf
And the girl who liked the teacher verbally bullied our mc and in the end didn’t even clear out the misunderstanding and gave her a somewhat happy ending bro I-

Man that tragedy tag really means tragedy
Everyone in this manhwa was trash besides mc, I kinda liked her but she liked her ex too much

I mean it’s not really the end but like-

Bro what

Aw there goes my heart again ending hurt like a bitch
I loved the bromance in this but this all ended in tragedy so no one is really happy, not even the reader

This was pretty dark

I had no idea what was going on lol

Aw man this was better than I thought....in a way
