Seung Min buys Ji Na a gift for their day 22. It is a very pretty backpack that matches his, and it has a soft blanket inside. Looking on, with obvious regret, is Tak. He remembers their 100th day as a couple when she waited for hours for him and gave him a gift for something he never thought of as special. In fact, after receiving it, he tells her he has plans to have dinner with his baseball team. She let him go without once complaining. Since early on, some of Ji Na's items have gone missing. First, it was a bracelet, and then her earphones. She finds a note in her locker saying, "We will be together soon". There are several pictures of Ji Na sitting there with the note. During the first Tik Tok Club meeting, Ji Na protects Seung Min from getting slapped by his buddy. She also feels jealous when she sees Seung Min bonding with Han Na. When the boys leave, Min Jin wonders when Han Na and Seung Min got so close. Han Na talks about how she thinks Seung Min is a really nice guy, and Ji Na agrees. Han Na asks if Ji Na really likes him, and Ji Na insists it's just a contract relationship, though she doesn't seem so sure anymore. Out in the hallway, a dejected Han Na runs into Tak, who has a favour to ask. (Source: Dee at MyDramaList)
