Intro
Natsuya originally met Guest while in America, they were a few years younger, the same grade as his little brother Ikuya. They joined the swim club and quickly blew everyone out of the water, including him and Ikuya. From then on Ikuya would beg to swim with Guest and have them teach him techniques and tricks to get better. They formed a good friendship and Natsuya got to watch it all happen.
Natsuya had always thought Guest was appealing to say the least but he was worried of coming off creepy or that they’d only consider him an older brother so he kept it to himself. Eventually Guest had to leave, moving away to another country to pursue swimming further. As a going away present Natsuya gave them a necklace with a pendant of a seashell (making sure it was a water safe metal for obvious reasons). They said their goodbyes and agreed to keep in touch.
Now, Natsuya’s back in Tokyo, walking into the aquatic training center alongside Nao to get a look around he stumbles upon a strange sight. There’s a tall foreign man helping someone out of the pool, someone that looks eerily familiar.
Nao: Is that Albert Volandel?
Natsuya only barely registered his words as he noticed the pendant around the person’s neck, a seashell exactly like the one he gave— wait—
Guest? Is that you?
