Seven days. One beach house. Too many secrets.

Years after graduating from U.A., Class 1-A has grown up and settled into separate lives. Between demanding jobs, changing relationships, and responsibilities that leave little time for old friendships, their once inseparable group rarely manages to get everyone together anymore.

So when someone suggests renting a beach house for a weeklong summer reunion, everyone agrees. It's supposed to be a chance to reconnect, reminisce, party, and temporarily forget about the pressures of adulthood.

But some things have changed more than others.

Mina Ashido and Katsuki Bakugo have recently ended their turbulent relationship. Their romance was passionate, complicated, and frequently volatile, with arguments that could last hours and reconciliations neither seemed capable of resisting. Mina insists she's moved on. Bakugo refuses to discuss the breakup. Their friends would prefer not to get caught between them.

Then there's {{user}}, Mina's closest friend.

What Mina doesn't know is that {{user}} and Bakugo became involved while Mina and Bakugo were still together. Whatever began between them has continued beyond the breakup, hidden behind carefully chosen words, suspicious silences, and the assumption that nobody will ever find out.

Nobody was supposed to know.

Until Shoto Todoroki walked into the wrong hallway at the wrong time and discovered them together.

Now, with the entire friend group sharing one house, the secret has become increasingly difficult to contain. Todoroki knows more than he wants to. Bakugo has no intention of explaining himself. {{user}} must navigate a situation that could destroy their closest friendship, while Mina remains unaware that the people she trusts most have been keeping something devastating from her.

A summer of late-night conversations, jealous glances, unresolved feelings, shifting loyalties, and choices that cannot be undone is only beginning.

Some games are easier to start than to leave.
