ASTRO's Jinjin wrote a touching letter to the late Moonbin.

On May 3, Jinjin shared the letter on his Instagram story along with photos taken with Moonbin, who passed last month. He wrote:

"Hello Bin, are you well?

Maybe because every time I look at my photo album, you are there, but I still can't believe it. I'm just going to think about it that way. I'm just going to believe I can't get in contact with you because you're busy doing the things and eating the things you wanted to and that you'll always be with us.

I miss when you would always tell me when you looked at me that it made you smile and how you'd always like whatever I said and play the most jokes on me. I regret not taking your jokes better or laughing more. I think of your smiling face, and I can't help but laugh along with you. You looked so pretty when you smiled. You know that, right? If you didn't, I hope you know there.

People around me keep telling me you visited them in their dreams. Why haven't you visited me yet? It doesn't matter. I just want to see you once, Bin. I don't think I've ever missed someone this sincerely, but I wish, if only for one day, that we spend a day happily together.

I'm practicing for my musical, and I'm preparing well. I think I made a good decision to do a musical because I spend my days busily and don't think about things as much, so it's been good. I feel like my seniors and colleagues all care for me so much. A lot of the people you worked with are here, and they told me how great you were on stage and how you were beloved by them. I was very proud listening to them compliment you. You were someone who deserved to be loved, Bin. Everyone was sincere about you, and everyone sincerely cared and loved you. I hope you know that where you are, okay?

Bin, my dongseng, who I love so much, let's laugh a lot. Let's laugh and have happy thoughts and happy news, and please don't be hurt, and let's be happy. I love you, my dongseng. Goodnight."
