Through his recent interview for the September issue of the fashion magazine Harper's Bazaar, actor Yoo Ah In admitted to be in a relationship. He said the following words.
I am usually someone who pesters myself, but as of recently, I am living life without worries. I think it might be because life has gotten easier, but I also think it's because I am in a relationship. I am in a very stable relationship. I used to think that severe love was the only kind of love that existed. Now, I admit to myself that love does not have to be so intense.
Some time ago, Yoo Ah In had indicated that there was someone important to him, but stressed that he wasn't in a relationship with that person at that time.
