Park Seo Joon and American actress Lauren Tsai are allegedly dating.

On May 22, photos of Park Seo Joon on a trip in Japan with an unidentified woman surfaced online, and netizens later alleged the woman was Lauren Tsai, who's known for starring in Netflix' 'Terrace House' and Marvel's 'Legion'. One netizen shared the photo along with the message, "Today, I came across Park Seo Joon. We were the only ones to notice, and the staff told us to keep it a secret. This morning, by chance I was watching 'Kill Me Heal Me' before leaving, and it felt like it was fate."

The photo features Park Seo Joon walking in front of a random woman, who netizens are claiming to be Lauren Tsai because of a similar purse. 

In related news, Park Seo Joon was previously connected to singer Xooos, but neither side ever confirmed the dating rumors.
