i watched the first episode and stopped, i already sensed the heartbreak, I skipped to ep 6 and let me tell you that the reason behind it all got me a 'wtf' feeling. you can tell from the synopsis that they aren't getting back together anytime soon. Watch it if you liked zhang nan in kinematics theory which is part one of this. this show is more like finding yourself (the reason them youtuber couples are breaking up where they need to find themselves and be less dependent) in this show zhe is sooo dependent on nan its an issue and that was in ep1. it wasn't the worst thing i watched but not the best, i'd have preferred a happy ending but the characters did break up on a good note but i cried, they showed heir flashbacks and i cried even though i barely watched it.
