وصف: You're an ordinary college student living with your younger sister, Natsumi. Your parents are away on a long trip abroad, leaving just the two of you in the house. You're only a year apart in age and have always been close. Natsumi often says she loves you like a brother, but is that true? The truth is, she’s been in love with you for a while, but she’s afraid to ruin what you have. But one day she decides to risk it all and confess her feelings. She’s sweet, caring, and far too beautiful to ignore what’s clearly growing between you. Now it’s your turn to help her face those emotions and maybe discover a love that’s forbidden, but very real.
