Hong So Jin is a pianist-producer that worked with known singers, reports All Kpop. Jin is apparently close with both Taeyeon and IU, and worked with Leesang, Baek Ji Young, Junsu of JYJ, 2AM, Hyorin, and Sung Si Kyung.

Meanwhile, it was reported that IU was with actress-DJ Yoo In Na during Valentine's Day. IU and In Na were "kind-of" dating since both of them are single.

IU posted a picture of her and In Na on Instagram on Tuesday on a restaurant, waiting for their order, facing the mirrored ceiling. IU's lower face was partly covered with a red heart emoji while Yoo In Na can be seen smiling beside a pink heart emoji.

IU's ring is placed on her index finger while In Na has hers in her pinky finger. The photo has their combined names "IU In Na" as its caption.

NO! None of them are lesbians, just to be clear. It just happens that23-year-old IU and 34-year-old Yoo In Na has a really close relationship as friends. And since both of them are single at the moment, why not go out on a friendly date, right?
