I'm not sure if it's the most romantic, but it's one of my all time favorites and it does pull at your heartstrings. "Sometimes When We Touch," by Dan Hill with Rique Franks (Best Version).

These are 4 of my favorite love songs, I still have enough, but they're enough for now
Asian: That's how we ended up - Giriboy (though it's more like a breakup song), an actual love song is me before you by Paul Kim
Non-Asian: Dark Paradise - Lana Del Rey
