I usually watch any drama after reading few reviews and judge whether it is worth my time or not and I did the biggest mistake by not reading the reviews in this one and directly jumped in to watching it because of the soul reason - VIN ZHANG
On personal basis, it was not a whole time waste for me as I got to learn one thing from the drama, infact, from the negative character, Lin Hao, is that when we have a breakup with someone who was so close to us and we loved them truly, we often romanticize their personality, their traits and everything, but in real when someone does wrong to you and you find yourself blaming your own self is the biggest sign that you are not wrong and above that, the other person is never going to change or come and apologize to you (in real sense). even if they do, they will be there for some benefit only and not because they love you just like LIN HAO. I find this cruel and not so comfortable thing very real in this drama. Yes, we do have so many Lin Haos moving around us and over lives- the ultimate manual of RED FLAG was portrayed by the single chatacter and that was simply outstanding for me.

The drama has the capability of making you frustrated by thinking that in the poster they have shown Vin Zhang as the lead but the whole drama has surely more frame of the negative character than the male lead.

Some good points about the drama:
1. The character Yan
2. The learning of how to deal with a toxic ex.
3. Han Shuang's dressing style.
sorry no other...

Negative points
1. LIMITED LIMITED screen presence of both the leads.
2. Terrible trust issues among all the characters makes me feel like how come they have. shown the solid friendship amongst the people who have basic trust issues.
3. Too much stretched. (utter wastage of time)
4. Non sensicle entry of ML's ex
THERE ARE MANYYYY MANYYY OTHERS!
