Kaii-san to Asuka-kun no Ohanashi

Synopsis

This is a problem. The more attached Asuka-kun becomes, the cuter he looks… Ever since Kaii-san picked up his lost commuter pass, Kaii-san has somehow ended up living in Asuka-kun's house...!? Eating meals together, trying their hand at gardening, spending Halloween together... Little by little, the distance between them seems to be shrinking. (Source: Kadokawa, translated)
