according to the novel, it's not entirely sahan's fault why philip khs. it was mainly bc he felt no sense of purpose when he came back from space.
after spending 1yr and eventually coming back knowing 11 years had passed, he felt like he had no reason to continue living. his brother grew up without him (philip thinks he was someone his brother needed in the past due to some circumstances), and then coming back just to witness that everything is already fine without him, he felt something more complex and depth feeling of despair as if he already witnessed what he had to witness in his life.
he had no reason to look forward to nor to continue his days. and almost the exact same thing will probably happen to sahan next season, but since heegeon is there for him, u can expect happy ending. so yeahh
