Miki really cares for her friend. She knows what Minato is like, and with what Koyun is dealing with from middle school, it is a recipe for disaster. Minato is a mess, but I can’t blame him too much. There are some clear issues regarding him; he needs some soul-searching. Perhaps he pities people because that’s how he views himself?
Koyun definitely was bullied in middle school and clearly has bad history between her and Igarashi. Which is also why Miki freaked out when she first saw him.
As soon as Koyun saw Minato and Igarashi together, it was inevitable this would blow up. Koyun pushes people away because she is scared and doesn’t want to get hurt. I can’t blame Minato for that because he has no clue what the history is like in middle school, but at the same time you understand why Koyun pushes people away.
