Summary

This little sister Riko can't show her true feelings to oniichan and even though she deeply loves him at heart, she shows a curt attitude instead. But one day oniichan broke both of his arms when protecting Riko from a traffic accident. While onii-chan has trouble with his everyday tasks, Riko helps him out. "I-It's not that I like you or anything, I was just asked by mom to do it!" Her caring covers not only your meals and bath taking, but also... "I... I love you onii-chan." [Edited from DLsite]
