I bet only because its in chinese its didn't got much attention. this series has 20 ep this season. and another 18 from first season. yes the first season is meh. it has bad animation. less interesting plot. but season2 is a masterpiece.the only problem i got with this sereis.
was the fact that each episode without the ed and opening.
are about 10 minutes its just not enough.
for the same reason.

those 10 minutes are top polished.
they are flawless.

the story is superb and unqiue.
the art is also really good in season 2.

the sound?
well surprise! the chinese isnt really that bad!
it's quite nice language can be fast at times.
but the female voices are wow! srsly.

the ED was amazing.
the OP was also amazing... (i one of those that skip yep was unable here).

characters :
the characters adapt.
and change quite a lot, we also learn about their past and that adds a lot
to the story. and thier development.

enjoyment.
this season was amazing so yeah
10/10

i truly recommend.
for those who are looking for a cool romance.
season 1 even if isn't great.
isn't bad neither, and is very enjoyable.
the biggest issue with s1 is the art.
its like 3/10 at most.
