Professor Ock gave the duo extra work for a couple of weeks but compensated them with a weekend in Japan. All expenses paid.

Yongsun came up with an excuse for her boyfriend and didn't hesitate to travel with the black-haired one.

Although the older girl planned a lot of tourist attractions to show Moonbyul, the transferred student just wanted to spend time with her.

Despite that, the younger one followed her colleague with enthusiasm and they had a lot of fun.

After a whole day out, they got back to the hotel and the dark-haired one told the stunning girl to wash up first.

Yongsun couldn't hold a smile with that cute demonstration of gentleness.

The 22-year-old ended up falling asleep and the brunette didn't dare to wake her up.

 _______ You still haven't responded to my proposal though.

_______ Okay. Let's do it!_____ The 22-year-old clapped her hands.

Blushing, the brunette murmured:

______ When you speak like that...what exactly do you mean?

______ Why? Are you afraid now, little bunny? You know that you are not a anymore, right? Even though I you superficially, we did lots of stuff.

______ Ah...I don't know how I feel. Sometimes I want you to destroy me. Other times, I am afraid of what people are gonna say if they find out what we have been doing.
