By a twist of fate, Evan Carter ends up living together with her high school classmate Ryan Grant, whom she once rejected, as roommates.

The two keep to themselves, like strangers living under the same roof.

Their peaceful life comes to an end one morning.

The night before, Evan Carter had slept in her own room, but the next day she woke up in Ryan Grant's bed.

Knowing she has a habit of sleepwalking, Evan Carter could only apologize and explain. But as this kept happening, she tried to negotiate with him, suggesting he lock his door before bed—

Ryan Grant didn't care: 'You'd pick the lock.'

Evan Carter patiently said, 'How could I possibly do that?'

'In order to share a bed with me,' Ryan Grant slowly looked up, speaking lazily, 'is there anything you wouldn't do?'

Evan Carter was silent for two seconds, then sincerely said, 'If I really was like that, would you be willing to lock the door?'

'......'

Evan Carter: 'Then go ahead.'

Ryan Grant: '?'
