We know Taeri is sketchy but I think there is a good meaning to what is happening.. just don't know what it is. Taeri you better be alive! We're still waiting for your come back!
I also think her classmate is the stalker.. since she knew about dayeon's marriage and maybe.. she likes dayeon that's why she is following Eunbi. I wish Dayeon finds her true love and be happy.
I bet Ina will do something more crazier just to get Eunseo's attention only to her.. Ina is like kinda obsess with Eunseo's attention only to her..
