Turns Out My Childhood Friend Is the Male Lead

They say she is a pure-hearted heroine, with male leads one, two, three, four, five, six, seven... and a sole male supporting character who dies because of her. They say she is a vicious supporting woman, whose beloved never loves her back, and who dies after being cruelly harmed by the heroine out of jealousy. They say... Wait, the childhood friend is the male supporting character? ※※※ Under the peach tree, they met for the first time that year. She tucked the peach blossom in her hand into the boy's hair, leaving a damp mark on his jade-white face, and said, "Pretty flower." Her master's laughter, clear as a breeze, came from beside her ear. The boy before her blushed as pink as the peach blossoms... Unbeknownst to them, a seed called affection had quietly been planted in both their hearts. But they were young then, unaware that the road ahead would be perilous and long. When they looked back again, everything had changed. Only that peach tree still blossomed year after year, but beneath it, the laughter and joy of that time could no longer be found... P.S. 1. The heroine is a native of this world, but the story includes transmigration and being reborn. 2. It should be a slow burn. 3. Every pit I dig is sure to be sweet.
