Ayaka no Himegoto♥

A young man is always exhausted because of his work and severe insomnia. However, what worries him most is his younger sister Ayaka's contempt for him. Although the two have never been close, they have lately grown even more distant as she constantly glares at him for seemingly no reason.

One night, the man notices Ayaka entering his room and pretends to be asleep. Shortly after, Ayaka reveals something utterly shocking—she is in love with him!
