A childhood friends love triangle

I'm looking for any love triangles between childhood friends. Preferably it's male lead/female lead/other guy, but it can be female lead/male lead/other girl.

The girl can like the other guy first, but then realizes her love for the main guy in the end like in May Queen. Or it can be she always loved the male lead, but due to circumstances, she's with the other guy like in Koinaka.

In the end, the male and female lead end up together.

Bachelor's Vegetable Store - Seen it and loved it. Though I am mad that Yoo-Bong didn't get that girl in the end even though it was clear they loved each other.

@Panda

Weight lifting fairy - Yeah, I couldn't get into it for some reason.

@RueXie

Summer's Desire - Eh, that disappointed me. I didn't like how it switched the male lead midway through from the first guy to her ex and then she ends up with her ex. When that happened, it started to drag really badly.
