Rena and Yuna have been roommates since school, and decided to rent a place together after graduation. They've lived together as friends for five years, but things suddenly change the day Yuna adopts a kitten, even though their apartment doesn't allow pets. When Yuna says she wants to move somewhere that will allow them to keep the kitten, Rena admits her true feelings: she wants to be more than friends. Yuna isn't sure how to reciprocate, but she's game to try!
