That event

Lee Jinhee opened her eyes when her arms were finally released from that grip, and her body fell onto the ground as her knees gave out. Crouching on the ground, she did not attempt to raise her head in order to look at Kwon Youngmi. 

Lee Jinhee had no idea about how long Youngmi had directed those blows at her for. Youngmi slapped, punched, and kicked her as much as she could in order to vent her anger .

When Youngmi was finally done with it, she ordered the maids to let go of Jinhee, and unable to compose herself any longer, Jinhee let herself collapse on the floor.

Her body was in utter pain, and tears formed at the corners of her eyes. She held in her urge to cry. She would not let herself fall weak in that moment.

She could not let Kwon Youngmi have the pleasure of seeing her crying in pain. That would only make Youngmi even more satisfied and was not something Jinhee wanted.
