Billlie's Mun Sua and Tsuki revealed their harsh dieting episodes experienced during their trainee days. Recently, they appeared on the YouTube channel 'Okiki' and had an honest talk about dieting. On that day, Mun Sua shared her most painful experience during her trainee days, saying she endured eating only ice for a week. She recalled, 'I was told to measure my body composition at the agency. I was already thin, but I wanted to lose more weight. Water felt heavy, so I ate only ice all day long.' She added, 'I was fine until the third day. But from the fourth day, I lost the sensation of walking. I felt like I was floating while climbing stairs. My weight at that time was 42 kg. It was the thinnest I had ever been, and I thought, 'I can never do this again.' Mun Sua warned, 'I could do it because I was young. I don't want anyone to imitate this dangerous diet.' Tsuki also revealed a shocking episode. She confessed, 'I once lost 4-5 kg by eating one candy each for breakfast, lunch, and dinner with an older sister I practiced with.' She further explained, 'When fitting stage costumes, I sometimes wear sizes that are really like children's clothes,' sharing the struggles unique to girl groups. In particular, Tsuki spoke about her experience of collapsing due to extreme weight loss, saying, 'I think it's a battle with myself, and even when I feel dizzy like from anemia, I endure it. One day, while I was enduring, thinking 'Ah, it's coming,' I lost my memory afterward and collapsed.' Mun Sua also expressed her thoughts on recent beauty standards, saying, 'Recently, the standard of beauty has changed to 'extreme thinness.' I don't understand why we have to talk about weight with each other.' She also opened up about the pressure she felt in the past, saying, 'My mother told me that maintaining a weight of height minus 120 makes you look beautiful.'
