Sea Sky Tropical Aquarium

My boyfriend is shy. After waiting for years, my unrequited love finally came true and we even kissed, but he won't invite me on a date. I've been waiting and waiting... Since there's no help for it, I've decided to give up on waiting for him to ask me out and instead invite him on a date myself. The place is an aquarium on a weekday. My goal is to go beyond kissing! But... I overslept!!!! *This is a side story featuring a supporting character from the author's serialized work "The Tale of the Crying Bird's Song." This continues from "Sakura (7)" in "The Tale of the Crying Bird's Song 2." Shuichiro, who somehow managed to secure a date... *BL warning!
