The only thing I can think of that would make Myeonggi avoid Jingi would be if the letter said something about Jingi doing something to kids. Like beating them up or sum bc Myeonggi has younger siblings that he cares for and atp that could be the only thing that rattles him after all he's been through.

LOCKING IN MY THEORY:
- Jingis uncle committed a child related crime.
- They strike some kind of deal, maybe to get his brothers sentence shorter or a cushy prison life?
- But Jingi takes his Uncle's place.
- The letter talks about child related crime.
- Myeonggi rightfully feels repulsed by Jingi because he thinks he's the one that comitted that crime
