You know I'm pretty flexible when it comes to my choobie headcanons I like big tiddy Chuuya and small chested Chuuya but if i had to pick I think Chuuya would be more towards the smaller side just to be proportional to Chuuya's overall frame. They aren't flat still a good handful, perhaps a B cup? Round and perky, nipples the size of quarters and a pinkish/tan color. Nipples are perky too always peaking through Chuuya's shirt😌
