I still don't want to run, but I run."

Regarding her diet, Lee Suhyun said, "I did not have a cheat day. It's very unfair." She added, "I resisted spicy hot pot and spicy rice cakes, exercised hard, and fight with myself every day to build healthy exercise habits. I am managing it properly for a sustainable healthy life.

Fans expressed concern about Lee Suhyun's weight loss. One fan said, "How much weight did you lose? You know health comes first no matter what, right? Take care of your health, sister."

Lee Suhyun appeared on tvN's 'You Quiz on the Block' and mentioned a period when she experienced a slump. She said, "I actually lived without seeing sunlight for a long time. I went into my room and started a hikikomori lifestyle. I only played games and ate delivery food. So I lived with the curtains closed. I didn't want to know whether it was day or night." She continued, "Every single day, without fail, I binge ate. When you gain weight rapidly, your whole body feels torn apart. I thought there was no better future for me."

She also shared how Lee Chanhyuk encouraged her exercise and diet management, saying, "(Lee Chanhyuk) keeps knocking on the door asking if I did cardio today, if I ran on the treadmill, if I sent photos of my meals. He doesn't stop talking. All I see is his mouth."
