Background / History

Lin Zhen transmigrated into the world of Love Full Courtyard six years before his promotion to engineer.

He married Lou Xiao'e shortly after they met. Before her family left, Lin persuaded his father-in-law to relocate the family, publicly sever ties with Lou Xiao'e, and transfer 30% of the family assets into the couple’s names for later use. 2
