I don't like this kind of situations. How to improve my line?

yeah for 6 max that's a ridiculous position to take. folding KQo to more significant raises pf is not a terrible thing to do, but in this instance you have to call.
you MUST bet the turn. it's an easy fold if raised and if he calls you again, you can either value bet the river or check/call depending on what falls.
the people who were advising you to fold this to the minraise are throwing money away.
