The ML and his sister's dynamic was a well written. How she is torn between the company and him is an amazing well written plot point.How these two grew to trust each other was heart warming to see. She always go back and forth from being protective of him to being protective of the goal of the organisation.

The 2ML well.. he was redeemable too in the end. He had growth he realised that it is not his to make a decision on the FL's life and kinda turned around for me.

The 2FL... I never disliked her through out the watch. It was more like seeing someone learning to understand love and learn that love is worth fighting for and not something to have in a convenient
Way. And with her she is not torn between the ML and the company she never was she was rational and business minded and admitted in directly that for the ML she is less special than the FL.

The squad? They were your one dimensional character line up but eh they were great fun to watch and how they switch up when they are serious is so cool.Only the manager dude got a lil depth and it's because he falls for the 2FL in the end.

The ML? He's whipped for the FL yet doesn't neglect his dream to go fast for the FL. He maybe childish but he's the lil push the FL need. He slowly by the last half started to mature and think about her opinions. He to me was the only character that didn't change much. Same passion. Same Chen mobai.
"Drive the car till it fly"

The FL? She slowly came out of her shell. It was good to see someone change for the better and smile a lil more. She is smart yet feel insecure about her abilities and the ML helped her navigate through it and "become her ocean" he was on the run to prove her right. The only person he slows down for.
I love her and the ML's sis dynamic too!

overall a good watch. the childish guy falls for the mature engineer.
nobody is watching it though so I shall keep this to myself.
