-Spoliers Ahead!-
Wow! What a masterpiece! Bless Trigger for taking on these kind of deep stories!
It's sad to see people in the comment getting butthurt over the ships. This isn't you average drama-bestgirl-wifu shit.
The story is very well written and focused on emotions and emotional pain. That's some advanced stuff most people are not mature enough to understand.
I love how well they did the character development. When the Chidori didn't want to give a rejection Tenga I was frustrated, but I was happy to see that they used that for her to grow and understand why rejection are important. Same goes for Maki. She was holding on to her pain the whole series, and refusing to let go. Until the very end, making her monologue the strongest moment of the climax, because it was backed with her own experience and decision to leave her fear of connecting to people.
The scene where the characters feel empathy for Katsuhira was worth the whole series!
This is going to my favorite list with a strong 10/10!
