If It's You, I Might Try Falling in Love. Volume 3

Ryuuji might seem like his normal self, but after making things official with Amane at the fireworks festival, he's savoring every moment he gets with Amane. The joy of being with one who loves you is something special-which makes it that much worse when a fluffy-haired senpai from another class sets their sights on his Amane... Aquariums, misunderstandings, and the first twinges of jealousy are afoot in volume 3!
