You can read a more detailed description at the source but basically a Korean netizen claiming to be Lucas’s ex-girlfriend accused him of: freeloading off of her (asking for luxury gifts, making her pay for things) and generally treating her like crap. The next day a Chinese netizen revealed that the Korean netizen’s experience had been similar to her own and that Lucas was two-timing them. Despite NCT stans' attempts at painting all allegations against gold-digging NCT member Lucas as fake, he and his company have owned up to them and have released your standard kpop pr apologies. The scammer will also be halting activities for the time being.
K*reaboo has two lengthy posts with the allegations: HERE and HERE

lmao guess all that money from NCT stans bulk-buying huge quantities of albums wasn't enough
