I didn’t know about this spin off lol. I saw this video on Tiktok talking about midari and I’ve seen both seasons of the anime but there are only two seasons out. It mentioned midari with another girl who was not mentioned in the anime and I haven’t gotten far enough into the manga to be able to know about her. I thought to myself, maybe she’s in this manga. I’m still not sure cause I haven’t read it but I’ll know one day! Just not today :’)
