Lucken didn't want anything to happen to Alisha and Diana, In addition to Duncan having a dark past, Duncan also has a temperamental nature and is also a psychopath who can endanger Alisha's life, especially Diana.
When Ducan was in rehab, he often injured several people who were there, especially people who worked in rehab.
Even Ducan once almost went to prison when he beat up a man who blatantly insulted Diana in front of him.
With all the events that Ducan has experienced, Lucken doesn't want Alisha to become a victim of Ducan's sometimes uncontrollable anger.
"Mr Lucky??? are you daydreaming?" Reyna asked while touching Lucken's knee when she saw Lucken was silent for a long time.
Lucken straightened his back as he woke up from his daydream.
"Hem...sorry Doctor Rey, I didn't hear what you said at all. What did you say?" Lucken asked with a slightly red face embarrassed by his reverie.
