Yup it is tragic and I would skip that chapter amd the next part where Ido grape Sejin at Sejin apartment. This scene does not end until Sejin make the ultimatum to escape from his unfortunate life
Judging by the pace, the rape would happen by Ido's brother at chapter 89, around the same time Ido went to the Grandfather's funeral. No wonder in the second timeline, the brother died during the funeral because of what he did in the first timeline
