Much more than a kiss

Summer and Valentine walked inside her apartment building, he made it clear to her that he'd accompany her to her door, still, she felt a bit dazed with her hand in his, it was almost as if she was walking inside that building for the first time as if the apartment that he was leading her to belong to him, not to her.

'SNAP OUT OF IT!' She inner shouted at herself when her door got closer. And she completely snapped out of it when Zack opened his door and then closed it behind him. He had a cap on his head that covered his eyes, and he locked his door without looking at Summer, not even once. He pushed his body too forcefully with his hand on his cap the entire time. She followed his retreating figure that broke into a run and then was out of the building before one minute had passed by.
