The author probably has no experience with romantic relationships. Is she a desperate wallflower, knows love experiences only from novels and movies? No feeling. Nowhere.

When the main couple's relationship should pick up steam, FL starts giving the boyfriend and viewers emotional cold showers. She gives lectures that are supposed to make her feelings clear, but sound like instruction manuals for vacuum cleaners. Only when she talks to ML about her ex, her time with him, and her suffering of the breakup does she come across as more emotional.

ML, an excellent, attractive man, the kind you rarely find, is just a constant gardener of this silly plant that rarely gets her appreciation.
In real life, most men would give up and wish FL luck in her expected new relationship disaster with the old hoodlum.

FL gets praised often and a lot. All the Mary Sue moments are annoying, unfortunately you have to endure that with almost all female authors.

Jonny Huang is great, while Li Quin has to portray an emotionally impaired person. She plays an emotionally cold person perfectly, although that probably wasn't intended. Never have I seen such a cold relationship portrayed. Too bad. LiQuin is a great actress and very sweet. Why do they do this to her?
At one point the script forces her to say, "If women had any sense, all men would be single forever." ...and men in hydrochloric acid are a solved problem, hahaha. Emancene bullshit!

Other forists have presented other actors, there is some misery. Well, despite annoying impairments, the series was sometimes entertaining.
However: I prefer to keep silent about developments towards the end of the story. There are some things that simply can't be depicted. However, we understood the good-human intention and thank you for the fish.

Last not least: I would urgently recommend the author to change her profession. Not only romances are not her thing
