Well maybe consider looking into what South Korean customs are like.
Entering any country to “meet a boyfriend/girlfriend” will set off alarm bells. Mostly that they’re worried you will stay illegally with them permanently.
Don’t pack too much. Have return tickets already (very important to show you intend to leave), be able to show you still have a life/ties to your home country.

2h layover is plenty of time. When you get off the flight at Munchen, ask the flight attendants for the gate number. As long as you go to the correct gate with the boarding pass, there is very little that can go wrong.
Read the rules on what you are allowed/prohibited to carry with you.
