Am on episode 2 of My Girl in my rewatch and Oh My GUH - Jeong Woo!!!!
He is, without doubt, my favorite 'other guy' ever - I adore him ridiculously much. It says volumes about how well the drama is done that despite the fact that I adore him so (more than a lot of drama leads), I still ship Yu Rin with Gong Chan instead. And not just because after the life Yu Rin has lead, she needs someone like Gong Chan - someone rock steady - after her father, the charming and untrustworthy gambler, Jeong Woo is not for her - there is no 'security' in him - he is an adventurer without a doubt and there is nothing she'd like to do as much as to give up that sort of lifestyle. Gong Chan is such a good guy btw - a rare kdrama hero who is really awesome - he is very kind to her even when she is nobody to him.
This said, I did adore them together and hope Jeong Woo gets an awesome gal of his own. Here is a shippy MV:

I have to say, if you ever wanted Jeong Woo and Yu Rin to hook up, watch the Taiwanese drama My Lucky Star - the story is basically what would have happened if Jeong Woo and Yu Rin were the OTP.
