To explain this scene as a novel reader, the ml drank all the alcohol that the mc hid as punishment for him hiding them. They later find out that the blue bottle of alcohol that Jimin gave the mc had an aphrodisiac that he didn’t know about when gifting it. This caused the ml to act this way.
They don’t find out that the alcoholic was spiked till a little while longer. They kinda showed that the ml was drinking all the alcohol the mc hid but it was literally one panel so it didn’t make it clear
