Heartbeat Delayed by Two Years

[Cool and reserved physicist VS unruly (early stage) dignified and arrogant CEO (late stage)] [Double childhood, double cleanliness, two-year-old sister-brother love] Before meeting Li Xingyan, Sheng Lin was a demon king among the disciples in the courtyard. He was either fighting or on the way to fights every day. He was a headache. After meeting Li Xingyan, Sheng Lin turned into a little fanboy, chasing her every day, or calling her sister, sister, sister non-stop while chasing her. His behavior was once reported to him as a way to bet on his freshness towards Li Xingyan. Some people bet for half a month, some bet for a month, and some bet for two months. The rebellious young master only said, "I will bet for the rest of my life!" When this sentence reached the ears of the Sheng family, everyone shook their heads and sighed. Grandpa Sheng: Girl Yan will be my grandson's wife, but she won't be your wife. Dad Sheng: If you dare to Huo Huo, my beloved disciple, I will break your dog legs! Sheng's mother: Son, it's not my mother who is attacking you. Just take a good look in the mirror! Sheng Lin:...... Amid everyone's unanimous disapproval, Sheng Lin vowed to catch up with Li Xingyan and then show off his affection in front of them no matter what. Imagination is beautiful, but reality is skinny. Li Xingyan put aside his emotions and devoted himself to the research of artillery shells. If he refused, he could only laugh it off. After experiencing repeated blows, Sheng Lin became more and more courageous, and finally embraced the beauty.
