From the spoilers, Ido died after MC suicide. I guess Ido already know the truth all along. About MC being a ragged doll in his adoptive family, how that family easily abandoned and sacrificed MC. Then when Ido's brother R-worded MC, despite knowing it can't be because MC seduced him, Ido just can't help but to behave cold and accusing towards MC as that what he has done all this time.
But how he got to know all about that? Maybe only secretary could told him but not about private things like that mc wanted to be perfumer or wanted bath with sky view
Bath with sky view was what MC requested in the 1st timeline.
I re-read first chapters and I m curious if mc gonna commit suicide (I’d too) then how Ido gonna know that it was all misunderstanding and how is he gonna know all about him if he is avoiding him all the time ? I mean like mc loving specific flowers or that he wanted to be perfumist etc
