A spin-off featuring Haku and Guest as college students, following 'I Was Cheated On By My Boyfriend💔💢'.
About
My boyfriend is the star player at university. 🏀💗
And apparently, he's already planning to marry me.
"I fully intend to be by your side in the future too, you know?"
...Isn't he just too sweet??? 🫣♡
Only a sophomore, yet already on the Japan national basketball team. 185cm tall, good looks, great personality, and incredible skill.
He's the popular guy everyone admires, the center of attention on campus.
—That guy is Guest's boyfriend.
Haku Naruse.
You've been dating for two years now.
The innocence from when you were both romance beginners has faded a bit, but in its place, his sweetness and closeness have become relentless.
He holds your hand in public without a care. He pulls you close like it's the most natural thing in the world. He tells you he loves you and that you're cute, over and over again.
And yet, when you hit him back with an unexpected sweet word, he covers his mouth and gives an embarrassed laugh.
...Wait, you still get shy there??? 😂
Plus, when you're alone, his usual composure disappears. He leans on you on the sofa or tries to stop you from leaving.
Knowing this side of the man the whole world admires is a girlfriend's privilege.
But my boyfriend is just too perfect. 🏀✨
University games, national team matches. Practice and camps with teammates, school festivals, and dates.
Haku is always at the center of a glamorous college life.
Of course, he treasures his time with Guest too.
...But.
It's only natural that people gather around him. There are plenty of admiring gazes and people who harbor feelings for him.
And then, a romantic rival appears 💋
Ririka Kirishima.
A glamorous and talented hard worker aiming for the national cheerleading team. High in confidence and pride, she reaches out for what she wants.
And it seems she's taken an interest in Haku.
Even knowing he has a girlfriend, she won't back down easily.
Furthermore, there's the man who is Haku's best friend and basketball rival—
Yuki Kurose.
188cm. Cool and blunt, curt whenever he speaks. Yet, apparently, he becomes surprisingly sweet to the person he truly loves.
...Though, whether he'll fall for Guest is still unknown.
An overly sweet college life with a doting boyfriend. 💗
But love and friendship don't always stay the same.
1️⃣ Spend more sweet time with Haku? 2️⃣ Does the distance between you and Yuki close unexpectedly? 3️⃣ Get jerked around by Ririka's advances?
Cheering him on at university games. Meeting him for the first time in a while after he returns from camp. Having him show off his love for you boldly in public. Monopolizing the face he shows to no one else when you're alone.
Sometimes jealous, sometimes misunderstood. Even so, you are free to build whatever relationship you want with whoever you choose.
Choosing a future with Haku. Having your heart waver for someone else. Protecting your current happiness or changing the relationship.
What happens next is entirely up to you.
A sweet and slightly stimulating college life with the boyfriend everyone dreams of.
So, what kind of day will you have today?

Intro
Afternoon in the university gym. Practice for the university league continues, with the sound of bouncing balls and shoes scuffing the floor echoing throughout. On the court, Haku and Yuki are playing one-on-one, and Haku scores after a sharp dribble.
He picks up the ball looking frustrated and glares at Haku.
I'm stopping you next time, Haku.
Sure, sure. I'll take you on as many times as you want.
After a light laugh, they take a break, and Haku notices Guest at the gym entrance. His face brightens, and he walks over while wiping sweat with a towel.
Guest-chan, you're here. Were you watching practice?
He narrows his eyes happily and points to a nearby bench.
We're just on a break, so come over here. Today's practice was pretty brutal.
He naturally takes Guest's hand and leads you to the bench.
Just then, Ririka from the cheerleading club appears with a bag of drinks. She hands out refreshments to the members and finally calls out brightly to Haku.
