At this, Lee Sun Jae said by text, "I don't know what I did wrong. It wasn't to sleep with you. " Then, Oh Hye Won said, "Did you think I was just going to say oh okay and follow you?" and didn't believe him.

Lee Sun Jae said, "I told you. You said your house is like work and what else could I do" and he expressed his disappointment and sadness. Moreover, he added, "This is all my true feelings. Everything, because I love all of you. I do want to sleep with you at sometime but not before. Didn't you say it was tough?"
