The actress' Instagram page had quite a number of pictures of Teddy, who is a producer. Last year, the actress even posted a short video on Teddy's birthday where she was seen kissing him on the cheek.
News of their split was confirmed by Han Ye Seul's agency, with a source stating that they have "decided to just continue supporting each other as colleagues."
The exact reason for their split is yet unknown, but reports claim that their busy schedules came in the way of their relationship. It is also not immediately known when they decided to call it quits, but rumours indicate that they have been having issues for quite a while.
According to one fan who seems to have "heard around the YG water cooler," Han Ye Seul was incredibly jealous. "When there was even a mention of Teddy on SNS she was right there saying things like 'he's so wonderful, he's mine, I'm so lucky that he loves me.' She demanded to know his every move and whereabouts at all times."
Meanwhile, Han Ye Seul's decision to delete her Instagram page has worried fans, who fear she is not handling the breakup well.
Teddy and Han Ye Seul got together in 2013 after a mutual friend introduced them. In 2014's SBS Actors Award, Han Ye Seul publicly announced her love for Teddy, saying: "...and lastly, I want to say, I love you, to my boyfriend Teddy, who I love very much. We loved much this year, and let's love a lot again next year."
