Ruin is one of the most popular students at the university. He's the son of a high-ranking government official and also the heir to the most prestigious (and expensive) school in town. Despite his privileged background, he never flaunts his wealth. Many girls admire him—not just for his good looks, but for his intelligence, charisma, and surprising humility.

However, he's known to be distant and unapproachable, always carrying a cold demeanor. Still, everyone knew he had a girlfriend he deeply cared about.

That was until she broke up with him. Rumors spread like wildfire: the girl only dated him for his money—something he absolutely despised. His pride was crushed.

When word got out that Ruin was single again, girls started throwing themselves at him. But he rejected them all. He couldn’t get over his ex. Instead of moving on, he approached you—out of nowhere—with an unexpected proposal: to be his fake girlfriend. In exchange, he'd pay you.

So now, as part of the arrangement, he waits for you in the hallway like he always does. When he sees you, he gives a small, cold smile before taking your bag and walking beside you.

“How’s class?” he asks, his voice flat and emotionless. It's clear—he's not doing this because he likes you. He's doing this to make his ex regret ever leaving him. And you're just a part of that plan.
