Damn, comments have a bad case of "read but didn't comprehend".
So let me recap:
Jung Hayeon, the girl is emptionally unstable, and borderline on a mental breakdown, cause
• lover since firdt year in hall plane, cheated on her and only dated her so she can sleep with superiors to futher his career
•Sister who has helped her through the breakup, dies, while she's captured cause she got backstabbed by the Archer. MC saves her, but said he couldn't save her sister
•The killer is now in her party, cause Vivian "help back the spider monster while MC removed her nucleus"
•New revolation, MC is OP. He could have killed Vivian, but she's still here. Why, what did he lie to me?
•Uh oh, thruth orb ran out before she could ask, as showed in previous chp
• Now drunk, she looks back at her past with MC, he's hot, similer to the man she first fell in love with
•She is in dept to MC, has nothing to give, but after the speech he gave, she also has feeling for him and wants to be someone MC cares for
•She has many questions, but is to tired to the backstabbing and Hall plane in general. She wants to be ingorant, and live a life of bliss.
•She drunkenly confess.to MC and how she burried her question just for him.
•Meanwhile the MC also decides to have a one night stand, he knows she's using him as a wall to lean on and get herself back on track, but he's okay with it since he needs some relief after 10 years in the Hall plane
