The adorable Navi-Jang Dong Min couple made comedian Oh Na Mi green with envy with all their lovey dovey antics on the March 15 episode of JTBC's 'With You.'

The couple had visited Oh Na Mi's home to give her tips on love and dating, and their cute, affectionate gestures brought nothing but empty laughter and scoffs from the single comedian. 

Navi and Jang Dong Min were busy finishing each other's train of thought, addressing each other with terms of endearment, and basically doing everything but giving the poor Oh Na Mi the advice that she wants.

Navi also bragged, "Oppa feeds me so much that I gained so much weight." Yes, we get it, Navi and Jang Dong Min, you two are clearly deep in love!
