No premiere date or PV yet. Check out the Crunchyroll article for additional information. Synopsis from AniList:
Uichi, once a happy and popular boy, is now the victim of cruel bullying. Then suddenly Yotsuba, his childhood friend and first love, shows up. How will this cute and kind-hearted girl try to help him…?
It’s kind of evil to have a character so similar to yotsuba but then have the topic so close to death and self harm
