PF facing shortstack push and cold call

CO is shorty and is 60/20. MP2 is 21/0.

I was more scared of MP2 than shorty's push. I was going to call it until MP2 called, then I got scared... What would you do?

3 folds, MP2 calls $0.10, Hero raises to $0.5, CO raises to $1.85, 3 folds, MP2 calls $1.75, Hero...

I fold. With 21/0 stats, MP2 prob has you dominated with a 77+/AQ+ but more likely a pocket pair. If you raise again, maybe MP2 drops out, but I'd rather fold for a better spot. I mean, that's about 1/5 of the stack in pre flop to just call. But calling seems worse then reraising because you get no fold equity post flop. It might be good if MP2 will check/fold if not improving to a set/TPTK post flop, but I can't see how otherwise.
