“Although I haven’t yet lived for a long time, including my debut preparations, [WJSN] is a dream I’ve dedicated about half my life to. Through that process, I became more mature and both cried and laughed a lot. Thanks to that time, I’ve also become more tough.

“Overall, I think my youth is WJSN.”

“When I was a trainee, it was really hard. However, I’m not the type to look backwards. I just look towards what I have to do and move forward only looking ahead of me.”

“You need luck as much as you need hard work, but since I’m the type to face the facts, I just focused on what I could do. I believe in not paying attention to things you don’t have the power to change.”

“In the past, if I had a goal, I’d wonder, ‘How can I get there fastest?’ Now, I wonder, ‘How can I get there enjoyably?’”

“Acting is fun. Around the time I had a lot of concerns, I ended up meeting a good project and good people.”

“These days, I just say this. If they say, ‘You’re like an idol,’ I say, ‘I am an idol.’ I can just break stereotypes by doing well. I just have to do well.”

“‘You don’t have to be in a hurry.’ [I would say to my younger self] That there are times when luck is with you and times it isn’t, but regardless, your efforts then will make who you are today.”

“Even if I were to go back to the past, I did everything I could, to the point where I wouldn’t be able to work any harder.”
