"My loving members, people who have been with me for the past 10 years and who I'm grateful for," Luna began. "Our pretty Sulli, I'm only now writing this post. Thanks to you, I laughed a lot and also cried a lot, we fought quite a lot, didn't we..?

The f(x) member, who was reportedly announced to not appear in her musical following the demise of Sulli, also called the late star as her "younger sister."

"I'm sorry I didn't take care of you more, love you more. I'll pray that our pretty Sulli will shine brighter in the pretty sky. I love you so much, I can't express my gratitude to you in words. You were such a lovely child and such a mature dongsaeng. I love you Sulli, I love you so much," she concluded.

Luna and Sulli debuted together in 2009, alongside Victoria (the leader), Amber, and Krystal. Earlier, Victoria also posted a heartfelt farewell message to Sulli on her Instagram.

The f(x) leader wrote, "Sulli, the weather is nice today. Goodbye. I won't forget you. I love you..."

Then, she also called out netizens who criticized her and her members for not posting anything on social media regarding what they feel about Sulli's passing.

"Since when have Weibo, WeChat, and Instagram become the rulers? The rulers by which we measure ethics, people's relationships, emotions, anything that people wish to measure. A public platform is a place where you can share things with others. When did it become a place to put on a show?" She wrote on her Weibo.

"If you want to see a show, then shout. If you want to create rumors, keep at it. I'm not extraordinary. I just want to live my life more grounded in reality than the people leaving comments," she added.

Victoria went on by asking netizens to quit speculating events just by hearing them from someone else and ruling out baseless gossip.

"If you have time to come up with a story, what do you think about spending that time doing something more meaningful? Please don't let [commenting and social media] become your life. You can't find your identity in a world that's made up of falsehoods. People need to take walks through reality. Please don't waste your time," she further said.

The idol-actress then asked netizens to stop dictating how someone else should live his or her life.

"Focus on your own life. Live in the present. If you live with a kind heart, that is enough," Victoria concluded.
