Kamen Katekyo to Pure NEET

Yuusuke has made up his mind to quit his long shut-in life and start college. A handsome guy named Haruki appears before him as his home tutor. Haruki's lessons are easy to understand, but there is a lot of touching and Yuusuke is constantly toyed with every day. One day, Haruki says, "It's normal to do something like this between friends," and helps Yuusuke masturbate...! This is an innocent story about a handsome, two-faced home tutor and an awkward shut-in who start off as friends.
