He's Isabella Gray's boyfriend in public. After every race he wants to see Sebastian first — and still won't choose.
Dominic is the charismatic star swimmer dating Isabella in plain sight, yet every afternoon he keeps ending up in the same lane as Sebastian — the teammate who calls him out and still shows up to practice. After every race he tells Sebastian he is the first person he wants to see, then refuses to choose. The trials are coming, the texts keep lighting up, and the secret cannot hold.
Between her and him is available on YourChannel through its official player.

The lane does not lie. Dominic and Sebastian chase each other up and down the pool every afternoon — "Can't catch me," "Looks like you'll have to stay late again." Then Isabella's message lands: "Dom, Mom made your favorite beef stew tonight. Don't forget, 7:00, babe." Dominic says he will finish this set and come up. Sebastian has just watched him promise core training in front of the whole team and vanish, and he says the quiet part aloud: "He's just Isabella Gray's boyfriend." The coach blows the whistle — one more 200m medley relay, and whoever is slowest shows up an hour early tomorrow.
That night Sebastian corners him by the lockers. "What do you actually want from me? To be your backup, to wait around for whatever time you can spare?" Dominic's defense is soft: "When have I ever wanted you and you didn't come?" Sebastian pushes the real question: "Be honest with yourself. What I have with you and what I have with her. Is it the same? Smile at her, call her babe, go home to have dinner with her. What about me?" Dominic gives him the truest line he has — "You're the first person I want to see after every race" — and then cannot deliver it: "Don't make me choose. I don't want to lose either of you and her. I won't let go of either."
Days later, watching Dominic grind through the pool again, Sebastian asks why he is pushing so hard. "It's not like I'm going anywhere," Dominic says. He notices the phone light up: "She sent 10. I replied to one. Do you think I care?" Before the trials, when Sebastian finally asks when he will tell Isabella, Dominic begs for more rope: "Just give me a little more time. Wait for me." The competition becomes his excuse not to choose, and the two boys in the same lane are both starting to drown.
Blond, built, and perfectly on-image, Dominic is the boy who smiles for the room. He is dating Isabella in plain sight, yet keeps turning back to Sebastian in the quiet between sets. Cornered, he is honest and useless at the same time — he says Sebastian is the first person he wants to see after every race, then refuses to let go of either person.
You're the first person I want to see after every race.
Dark curly-haired, sharp-eyed, and always the one left waiting, Sebastian is the swimmer Dominic cannot quite drop. He calls Dominic out to his face — "What do you actually want from me? To be your backup?" — and still shows up to every set. He notices every text the moment the phone lights up.
Smile at her, call her babe, go home to have dinner with her. What about me?
Blonde, composed, and always knowing the family dinner time, Isabella is the girl everyone believes is Dominic's one and only. She texts about beef stew at seven and calls him babe. She has no idea that Dominic keeps a small gift he bought for someone else hidden — the kind of secret a girlfriend in public is never supposed to know about.

Our editors' notes on the opening arc — personal picks, not audience feedback.
Dominic is not written as a villain. He is a swimmer who says the truest line on the show — "you're the first person I want to see after every race" — and then refuses to choose. That refusal is what makes the pull hurt on both sides of the water.
Isabella is not a schemer. She is the girlfriend who texts about beef stew and calls him babe, and the entire secret orbit is quietly arranged around her. The tension is not that she is mean — it is that she has no idea.
The 200m medley relay and the trials hanging over every private moment turn the pool into a pressure cooker. Dominic keeps using the competition as his excuse not to choose, and the water stops being a backdrop and becomes the reason the secret survives.
Best for viewers who like love triangles with a sports frame and a boys-love core; if you need a lead who makes a decision early, this one drags its feet on purpose. Compared with most triangle-shorts, the show lets the unchosen girlfriend be a real person rather than a punchline — that focus is both its strength and its limit.
