Su Wanwan passed away with regrets in her past life, but was reborn back into her campus days. She accidentally discovered that Shen Mobai, the plain-looking and silent male classmate wearing black-framed glasses at the same school, turned out to be a future tech elite and the only son of a top-tier Beijing family. This time, Su Wanwan decided to proactively approach him and no longer miss out. She approached Shen Mobai under the pretext of asking questions about advanced mathematics, delivering milk tea, and bumping into him in the library, stepping into his world step by step with sincerity. She originally thought it was just a fateful encounter rewriting destiny, but she never expected that this outwardly dull and slow-witted science-and-engineering guy had long used the purest and clumsiest deep affection to spoil her into the priceless treasure of his heart.
