Stray Kids are staying sober in their first year. 

In 2019, the members Hyunjin, Han, Felix, and Seungmin have officially become adults in Korea. During an interview with News1, they are asked what they want to do after turning 20 years old. 

Hyunjin first answered, "I don't think my daily life will change that much just because I officially become an adult. However, there are several promises. As now I'm an adult, I want to be more attentive with my work and act with more maturity. Also, I personally want to travel."

Next, Hann said, "I want to watch late night movies with 2000-ers." Felix followed, "There's nothing specific I want to do after turning 20. I'm just looking forward to myself as an adult." 

Lastly, Seungmin said, "I want to be able to make small cell phone payments on my own. Teens need parents' permission for small payments. I had to get my parents' permission when I sent birthday gifts to my friends, but now it's nice since I can do it on my own."

The next question asked if the members drink together sometimes. Bang Chan answered, "I haven't been drinking because of a promise we made. I promised the members not to drink for a year after our debut. I think it's rather a time for us to focus on promotions."
