Sinb and Sowon has been dating for years now but its not a secret how possessive and jealous Sowon is with Sinb especially when she is with her bestfriend Yerin.

 Because Sowon knew how Yerin had once confessed her love for Sinb but just gets rejected because Sinb only see Yerin as a friend and a sister too.

  They are childhood friends. Yerin became part of Sinb's life even before Sowon became part of it. So you cant really blame Sowon sometimes because she just loves Sinb so much.

 Its not that she doesnt trust Sinb but her insecurity is just greater.

 But despite that the three together with their other friends Yuju Eunha and Umji are friends with each other. 

   Sinb finds it very cute everytime Sowon is jealous. Yes, sometimes its getting annoying but she understands. And because she wants to see that jealous side of her, she purposely makes her jealous with the help of no other than Yerin.

   Sinb ah, where are you? Sowon asked over the phone

  Babe, im with Yerin right now. Her parents invited me for dinner. Sinb answered

  Ah, okay.. Sowon said 

Babe, i will ..Sinb  words was cut when Sowon immediately end the call

The a loud laugh from 5 people were heard.

She is probably jealous again. Yerin said

She is still really that jealous with you Yerin. Eunha added

Its been years already and I already have you anyway. Yerin said then winked at Eunha

Eunha then blushed. 

Stop with the flirting you two. Yuju said

Coming from you? Then why are you hugging umji right now? Yerin said

Can we stop now? So what do we do with Sowon now? Umji asked looking at Sinb

  Honestly i dont get her jealousy too sometimes but i guess she is just afraid to lost me, well cant blame her anyway. And she is so cute when she is that jealous. Sinb proudly said
