Many more people were brought to tears after reading the letters left to Moonbin by all those he left behind.

Countless fans have visited the memorial space prepared by Fantagio and left messages for the late idol. It has been five days since Moonbin's passing and fans still do not want to believe that the idol is gone. Many of those who he left behind continue to mourn and show sorrow for the late Moonbin.

Among those who paid a visit to the memorial space were ASTRO's Jinjin and MJ, and Seventeen's Seungkwan.

They left heartfelt letters to Moonbin, bringing pain and more tears to fans.

Jinjin wrote, "Bin, it's Jinjin Hyung. Many people came (to the memorial space). You made a promise to me right? to live smiling.  I'm putting effort to smile just as you told me to. I'm going to start practicing for musicals and I'll also eat your share of food too. I'll care for your mom, dad, and Sua, so don't worry. I love you so much. My younger brother."

MJ wrote his letter and posted it right under Jinjin's. He wrote, "My brother Bin. I came too late. I'm sorry. How lonely and difficult it must have been for you. Only if I was closer. I'm sorry I wasn't able to protect you."

Moonbin's best friend Seungkwan also left a letter. He wrote, "Moonbin, please wait a little longer. I'll make the whole universe feel like it belongs to you. I love you a lot, a lot. When we meet again, please hug me tight."

Other celebrities have paid their visit and also left heartfelt messages to Moonbin. His younger sister, Sua of Billlie, also left a letter for her brother.

Meanwhile, Moonbin passed away on April 19, when the idol was found dead in his apartment at 8:10 PM. Moonbin's funeral procession and burial site were not disclosed at the request of the bereaving family. Instead, Fantagio set up a memorial site for fans to visit and pay their respects.
