He always goes home before sunset, because that's when Jin Shisu needs him most.
Lin Yu blurted out "Let's break up", causing Jin Shisu to kneel on the broken glass.
Jin Shisu's illness broke out at sunset. The moment the sun sets, separation anxiety will drag him into the darkness - he will freeze, lose his hearing, and have a recurring nightmare: Lin Yu says he doesn't want him anymore.
