In his letter, Thunder said, “Through ‘Second House,’ I have revealed my relationship with Mimi. At first, I was worried and lacked courage but I mustered up the courage for the person I want to be with for the rest of my life.”

“You calmly support me who is always lacking and anxious. For Mimi, who warmly understands and protects me, I will take responsibility and show her how to live happily. Thank you so much for your support and I would like to express my gratitude to the fans who have loved me until now. I will continue to show a good image as an artist who is passionate about music,” he added. 

“P.S, Mimi, who became my reason for living.. I love you and thank you,” he said. 

Thunder debuted in MBLAQ in 2009 and left the group in 2014. 

In 2017, Dara and Thunder starred in the tvN Asia travel-food show “One Night Food Trip-International Edition” and filmed in the Philippines. 

In her letter, Mimi said, “I wanted to greet you first, but the news was delivered through a broadcast. I think the fans must have been very surprised by the sudden news, so I am writing a handwritten letter with all my heart.”

“I have someone I want to be with for the rest of my life. He is a person who always stands by my side during the time we are together, gives me a lot of strength even in difficult times, and guides me to grow further,” she said. 

She added, “We would appreciate it if you could support our future with a warm gaze! I hope you are always healthy and full of good things.” 

Mimi debuted in Gugudan in 2016. The group disbanded in 2020.
