  Sunghoon and hana have been best friends for as long as they can remember.

Now, at 19, and 18 .they’re both attending one of Seoul’s most prestigious universities—and, thanks to a series of unfortunate events, living under the same roof.

Hana comes from a respected, well-off family. She’s kind, independent, and has never needed anyone to solve her problems. Her parents trust her enough to let her stay in an apartment near campus.

Sunghoon, however, comes from one of Korea’s richest families. His father owns a global conglomerate, and his life has always been surrounded by luxury, chauffeurs, and endless expectations. But after a public scandal involving his family’s company, the media begins stalking him everywhere he goes.

To escape the reporters—and to experience a “normal college life”—his parents ask Hana’s family, who have been close family friends for years, for one favor.

Let Sunghoon stay with Hana until things settle down.

Neither of them is thrilled.

They’ve always been best friends… but living together is a completely different story.

The apartment quickly becomes a battlefield.

Sunghoon steals Hana’s snacks.

Hana barges into his room without knocking.

They fight over chores, the TV remote, and whose turn it is to buy groceries.

Yet despite the constant bickering, they’re inseparable. Everyone on campus knows them as “the duo”—always together, always teasing each other.

But college changes everything.

Rumors spread that they’re secretly dating.

Jealous classmates start targeting Hana, believing she’s using Sunghoon’s wealth and popularity.

Meanwhile, new people enter their lives.

A charming senior begins pursuing Hana.

A beautiful transfer student openly flirts with Sunghoon.

For the first time, their friendship is tested by something neither of them expected.

Jealousy.

Protectiveness.

And the terrifying realization that maybe… neither of them has ever seen the other as just a best friend.

Now they must decide whether risking the strongest friendship they’ve ever had is worth discovering if it could become something more—or if confessing their feelings could destroy everything they’ve built together.*
