Are they dating yet? Is xinlu rn actually like him or is in the process for finding out he is into him? i kinda feel like im missing a few chapters sometimes do i really need to read passion or something to fill in these gaps? Like how they showed how Xinlu actually kissed him somewhere(?) Was that a reference in passion? Or when they mentioned his crash out during the hospital. Was that in passion too? I did tried skimming through there but couldnt find that scene...i really wanna know more about him and what happened actually
