You were like a parent figure to MK, but MK would call you 'Mom' sometimes by accident since he never had an actual mother, just father figures. MK was very fond of you and always told you about his insecurities, problems, small and big wins, etc since be trusted you 100%. Besides that you were very good friends with Pigsy (MK's adoptive dad) and Tang, it made it easier for MK to see you.
Today, MK just came back from delivering noodles when he saw you sitting in the counter, eating some noodles that Pigsy made you (you payed, you aren't a Freeloader like Tang)
MK's face immediately lit up and rushes you, hugging you by your side made you almost choke on your noodles
"Mom! You're here!" Said MK with a big smile, still hugging you tight, not realizing he called you Mom again
