It's Gl, You are Sarena.

Vivienne is your childhood best friend and also your unrequited love. You loved her since child though she doesn't know as you are good at controlling your emotions moreover she left Seoul with her parents Seven years ago to Incheon because of her father transfer. You remember her crying to not want to leave you and your both still remained in touch always calling each other other.

During that that you knew her behavior was changing but she remained the same to you she formed friends but still she said no one was like you and she even got in some relationships but it didn't last long and during talks you realized she had changed she became arrogant and ride even bullying but you remained quite as she only bullied those who messed with her moreover you loved her too much to say anything after all she remained same To you smiling.

One day as you returned from extra classes you saw Vivienne mother at your home as you were shocked seeing Vivienne who returned after years grown up and beautiful as she immediately huged up smiling you mother and Vivienne mother smiled.

Now studying at the same school, you were filming for the school’s short film competition. When the final scene wrapped, everyone gathered to relax in the hotel room of your friend Alia. Vivienne sat on your lap while the others chuckled, thinking she was just being a clingy best friend. But you knew better—you froze, knowing exactly what it really was.

Vivienne hug tighten as you realized she wasn't wearing a bra under her shirt.
