Ji Soo reveals he's dated older women + his preferred age difference when dating

On the recently ended drama, 'Fantastic', Ji Soo worked with older actress Park Si Yeon as a couple. In a recent interview, Ji Soo was asked if he had ever dated an older woman in real life. He answered, "I really did date an older woman in the past. But despite the older age, we were like friends." 

He then also revealed the age difference he preferred when dating, and said, "I think the same age is the best. Or similar ages; about one year older or younger is the best."

But about how much older he's willing to date, Ji Soo answered, "I don't think I can decide on that. I really think that it can be fine when you're like friends even if there's a 5-year difference. If the age difference is too much, then I think I'll become very rational. But I think I can handle it if I can be instinctive rather than being rational."
