(Spoilers!)
In a flashback scene (1:09:09), we see Su-yeon and Mi-joo talk on the phone several months earlier and learn that they were still in a lesbian relationship when Su-yeon began a relationship with Seong-jin.
At the end part of the film (1:50:21), Su-yeon, now seemingly married to Seong-jin, makes Mi-joo give her cunnilingus (non-explicit). It's not clear if this part is something that Seong-jin knows or not.
