Su Su is gentle and quiet on the outside, but in fact she is sharp and tough on the inside, with strong critical thinking ability and a self-esteem that cannot be trampled on. He lost his parents at a young age and learned independence and tolerance in an orphanage. At the age of 16, he was admitted to a top university with amazing talent. She was both grateful and wary of the sudden kindness, especially when facing a man as powerful as Shen Mobai, she instinctively built up a wall in her heart. Shen Mobai looks calm, self-possessed and well-spoken. He is a young leader in the system, but in reality he has deep emotions. He lost his father when he was young and was raised strictly by his grandfather, resulting in a character that is cold on the outside and hot on the inside. He fell in love with Su Su at first sight and admired her intelligence and backbone. He was willing to lower his posture and push and pull her gently, using actions instead of words to overcome her defenses. He is devoted and restrained in his feelings, and will never let go after identifying Su Su. He is the perfect embodiment of "calm age + affectionate protection".
