Transmigrated to Before My Lover Made It Big

[Easygoing, healing sunshine transmigrator heroine vs. outwardly gentle but secretly ruthless, taciturn, possessive regent] Yu Suisui transmigrated. Unfortunately, she wasn't a crown princess with a political power-play script in hand, a concubine-born daughter who needed to turn her fortunes around in a household rivalry, or a farming heroine who could build a fortune by taking down awful people. She was brought home as the regent's wife the moment she arrived. The current regent is ruthless and all-powerful, a hard man who makes children cry at night. Everyone turns pale at the mere mention of him. But he treats Yu Suisui well and is the person she relies on most in this world. Now, however, this protector of hers has fallen ill. An old monk tells Yu Suisui that she must visit him at three different stages of his life: his childhood, his teenage years, and his early adulthood, to awaken his memories and bring him back to consciousness. To that, easygoing Suisui says: “...This is going to be tricky~” P.S. This is the story of a heroine who transmigrates into the different periods of her beloved's youth and heals a gloomy, possessive big shot.
