Reincarnation of the all rounder miss I can you can

In her previous life
Su Ran was the no.1 killer S
After destroying the organisation behind all her sufferings,she fell into depression
Afraid that she will lose herself,she burns herself to death ending all her sufferings and embracing freedom
But she found out that she did not die but reincarnated in her biological twin sister’s body whose name is Yu Yan
This reincarnation not only fulfilled her wish of having a family but also let her experience the life of an ordinary person
Li Yifeng is the youngest major general in the country he is 24 years old cold hearted,ruthless,upright and righteous
The first time Li Yifeng saw Yu Yan she was lying on the ground rubbing her injured knee looking pitiful like a helpless abandoned cat
All the killer organisations in the world:We don’t know the same person !
The second time Li Yifeng saw Yu Yan she was smiling brightly at him his heart skipped a beat and then started racing,he was feeling as if he was stepping on the clouds
He didn’t know what he was feeling so he went home,took out his phone and typed:”explain all emotions of the world”
After two days-
Li Yifeng said to Yu Yan:”I-I-I I LIKE YOU”
He spoke so loudly that all the passerby stopped and turned to look at him
He felt so embarrassed that he can’t wait to lie down pretending to be death
But he still firmly locked his gaze upon the person in front of him
