When Yui’s apartment burns down, the last person she expects to offer her a place to stay is her quiet, awkward classmate Haruki. But with nowhere else to go, she moves into his tiny college apartment—and nothing is ever the same again. What starts as a reluctant arrangement quickly turns into something far more intimate, filled with late-night talks, shared meals, dumb jokes, and slowly growing feelings. As they learn to live together, are they just roommates by circumstance… or soulmates by fate?
