"I can do it right , tell me what should I do Umji?"  Sowon asking her little sister

   Umji- Sowon's little sister and the only person in the world that knows about her feelings towards her bestfriend Sinb.

     " Just confess to her unnie, dont think about anything else and just worry about the consequences later. You wouldnt know her feelings if you wont even try at all". Umji reassurres her sister

   With her sister's support Sowon then decided to confess tomorrow. Sowon finds it hard to sleep that night, writing her letter this time with only pen and paper. No more computer to help her

hide her identity from Sinb..its now or never.

   Then the next day, Sowon as usual put the letter to Sinb's locker hoping this will be a good day for her then she immediately walks away.

      Coincidentally Yerin was there too and saw what Sowon did. Yerin is not aware of the encoded letters Sinb keeps receiving from someone not until Yuju her little sister and also Umji's girlfriend told her about it.

   Yuju overheard Umji and Sinb talking and ask Umji about it. Umji was so hesitant at first but she doesnt want Yuju to get mad at her so tell her about the anonymous letters but leaving out who the writer is whom Umji only knows.

    Yerin out of curiosity took and read the letter and from then on she knew who the mystery writer is. Its no other than Sinb's bestfriend Sowon.

     She know her chance to Sinb
