The Story of Kaii and Asuka

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...!? They eat meals together, try their hand at gardening, spend Halloween together... Little by little, the distance between them seems to be shrinking.
