oh ok..it was a flashback...that would be really fucked up if they would now sleep together...
so sumin didnt cheat on sungji...
sooo...thats what i think..
Nami was interessted in Seju from the first time she saw her. She befriended herself with Sumin. Seju cheated on Sumin. Sumin broke up with Seju. Seju still loves Sumin after 10 years. Sumin is the only reason Seju is still breathing. Seju probably thinks that you can only truly love one person in a lifetime. Nammi, after trying to sleep with Seju, realises that its impossibl for Seju to feel something for someone else than Sumin. Sumin, after breaking up with Seju, starts to date other women. But unfourtunetly Sumin and the women never fit together. In this 10 years Seju was always next to her. As a Friend, as a sex Friend, as an ex lover.(,...as her only family?) But always staying true to her feelings.,,Seju admitting bluntly she would only marry Sumin. Of course Sumin would take Seju after 10 years of admitting for granted. Its like Seju is her belonging. Sumin liked it. She got used to it. But ..it`` was a human too. She never expected Seju ever to go off the dog leash. Sumin trying to hurt her even more to get her in her old place (Something about,,"All you do is disappoint me all the time!").
I would really like it if Seju would find another reason to life.
But....
I think it will be like... Sumin will somtime feel shes losing her pet entirely, so she tells her what she wants.(that she loves her and dont want to live without her). They get back together. Seju will forgive/forgett everthing that Sumin did to her in the past. And Sumin will forgive Seju, of what had broke their first relationship...and they will live happy together till they get annoyed with each other and break up because they will realise it was about possess and not love and move both on.
:D somehow my thoughts turned out like that. Didnt plan it xDDD ....and of course everything that i just thought could be wrong ^^ but it was fun writing ~o~
