Nah you're misunderstanding. The first time it was intentional but it was way before he came to know how deep their relationship was. This time he literally said it wasn't intentional, so there's no need to assume he was lying since he's been a real friend for Wooyoung. Let's just remember how bad Wooyoung treats him, always hitting him, calling him names but then relying on him when he feels lonely, needs a pickup or he's drunk af. Also, the day of the "date" he was forced to go with them cause ML wanted to test them to see if they were in hangover from the night before, he almost puked, didn't want to be there for sure

What Liam did was missed up and him trying to use the dominant alpha card is messed up to a alpha should never release thier pheromones on a omega like that especially if the alpha knows they are in a relationship its rude and messed up and the fact that he did it twice on him or to even more people makes me mad
