Pluto

Ai-oons identical twin Ob-oom is in a tragic accident the night of her wedding. Ob-oom survives but is left in a coma and her husband doesnt make it. Helpless to do anything for her sister, Ai-oon resolves to do her the favour shed refused hours earlier. This leads her to a woman she could not have prepared for her, a woman she finds herself drawn to even as she questions whether she could have been involved in Ob-ooms accident.

Ai-oon realizes how small her position is in her grandmothers heart compared to her twin, as she also has to face complicated feelings between falling in love with May and realizing that Mays love isnt for her, but for Ob-oom.

Jealousy ensues when exes are visiting

Ai and May go to a party. Heartbreak follows after some misunderstandings.
