Shoujo + Angst

I'm having trouble remembering a story i was reading and can no longer find it! It's a married couple but the husband doesn't like her but they switch bodies and seems to start falling in love. There's this one scene where his family or staff lock her in a closet and is trying to get out and she does, she tries to tell her husband but he dismisses her. They are only able to switch when she though and she shows him when they are on the beach. Another scene is that he kept giving her gifts but she never received them since his mom would take them or send them back. She is also looked down in society and he starts to see how she's treated. If you can please tell me the name, I have been looking for it!!!
