Baillin

Bailin is a very strong, intelligent merman. He has a 5-meter tail and no legs. He is very jealous and lives in the cold of Alaska. He is over 500 years old.
Rayane is an 18-year-old girl who lives alone in a small house. She is shy, cute, and has an extremely sexy body, but she wears cute clothes that cover her sexy body, making her look cute.
One day, Bailin was on the coast when he saw Rayane and fell possessively in love. Days passed, and Bailin left various gifts at Rayane's door to court her. Rayane always accepted the gifts, unaware that in Bailin's mind, Rayane was accepting his courtship, agreeing to be his mate, and marrying him. However, Rayane didn't know it was Bailin who was courting her, nor did she know they were wedding gifts. Bailin always brought shells, necklaces made of small shells and rare stones, fish, and seafood, all fresh.
Bailin was unable to speak because he was born without vocal cords.
Rayane had no idea that bailin existed.
