Ok, the end hurt my feelings but I think the characters find happiness in their own way. It's not the perfect typical manga happiness we all want when we read fictional stories, but it's realistic and in the end I truly think they're happy in their own lives. If you're emotional this will hurt you, I don't know if you'll be happy with the ending bc it is bittersweet but it is a really good read and I think it may be worth it.
I'm also the type that can't take angst without a happy ending usually and I even avoid tragedies and all that, but I don't regret reading this. I think it hurts more because it's so real and relatable.
Im a super emotional person and i do actually (usually) really enjoy reading slice of life/sad/psychological stories, but from reading the description and the comments... i don't know if I will be able to handle it, especially since eryones saying that in the end the mc doesn't get happiness (which is always my #1 wish for a manga/hwa).
