Binged watched a show after a long time, every single epsiode had clues,twists and turns and if you watched the entire series you'll notice them properly
Spoliers ahead
1.oh sung had crush on his step sister that i suspected from the first scene itself
2. Ok chankyu being gay was also a doubt when he faked his girlfriend and also considering his conservative parents
3. Sejin dating ok chankyu was suspectable as soon as i saw the scene where he recorded him while smiling
But idk why he hided this fact till the end.
4.jaebum being the murderer was unexpected
5. Chemistry between main leads was 0 then also they ended up together i mean there wasn't any need.
6.Sejin being raised by gay couple then he also coming out as gay really sends a wrong message
7.writers should have let the main lead graduate
8. Rapist wasn't punished well,
9.the twin theory was suprising but felt like a possession rather than mental illness
