After saying that, Shin ran out while Ruina and Kenny patted their foreheads hearing Shin's excuse, because it didn't make sense, even though drinking water was already in her left hand and how would she buy another drink?

"Jealousy makes her dehydrated so she needs a lot of drinks, so you don't have to be surprised?". whispered Ruina to Kenny who still looked surprised at Shin.

"Why doesn't she just put poison in her drinking water. So, her heart is calm as long as she does it". Kenny said expressionlessly. Ruina was immediately taken aback by the chairman's cold and stiff comment.

"Isn't that too cruel?".

"Better so". Kenny continued again with a smile.

"You come too?". YK greeted kindly while interrupting Kenny and Ruina's chat.

Hearing the soft voice of a woman with two different faces made Kenny and Ruina turn their heads at her.

"Looks like someone already accompanied you, so we want to say goodbye". said Kenny expressionlessly.
