I'm so tired. They're all crying over extremely different situations. In this particular scene, Khem was scolded by the person he likes romantically, and that's why he's crying silently. It's extremely stupid to judge his skill without considering the situation he's in.
justo vi que andaban diciendo que debería llorar más fuerte o cosas así PERO SI USTEDES CREEN ESO ES PORQUE DEFINITIVAMENTE NO ENTIENDEN EL PERSONAJE DE KHEM
