Melt me with your voice - Lion-kun's sensitive ears ♡

On the day of the entrance ceremony, I fell in love at first sight, for the first time. Hikari, a lion, is dependent on Rika, an Impala, whom he has feelings for. While Rika is taken aback by Hikari's boisterousness, she cannot leave him alone because he is so cheerful and kind. The two go to Rika's house to help him with his assignment. Hikari is thrilled to be in Rika's room for the first time and hear his favorite Rika's voice all the time. Then, by chance, Hikari finds an H-book (*and a boy who looks just like him is being groped!) ), and he finds a book. Why don't we do it like in the manga?" Rika can't stop herself from seeing Hikari's debauched expression for the first time. How did this exciting first experience end?
