After transferring to an elite institution, facing peer exclusion and external forces tangling, she resolves them one by one with calmness and wisdom, making a group of close friends and confidants. Internal conflicts within the Ye family frequently erupt due to family affairs, and the seemingly stable wealthy family and campus harbor many trials. The sealed past continuously brings severe tests, and she will recognize herself amidst predicaments, guarding those she cares about around her with heart.
