Story- This plot gives us the right view of the current society and the value of self awareness. the representation of the two boys with different goals and views to meet and lash with misunderstanding. Which later leads into their up coming and the beautiful reality. And do i recommend you to watch this?
Yes, its a beautiful story but YOU should be emotionally strong.

Acting/Cast- The acting was on point, their emotions , their gestures , their expressions and everything.the cast displayed it all perfectly. Billkin and PP did their best and they did amazing. Also the plot setting was a plus point to all the feeling it gave out, the perfect mood for the situation.

Music- The OSTs are basically AMAZING. Especially 'Skyline' even though its a very heart breaking (i still listen to it) the lyrics have a beautiful meaning. The usage of the Chinese language creates a very refreshing attitude.

Re watch ? I would say no but also yes because it was an emotional ride and heart breaking at times.and yes just because it just gives you all the feels
