hello anon! this is so cute! not a silly question at all~ i actually like entertaining questions like these. 😆 surprisingly, i'm not a sweet tooth nor fond of baking. though i do have it/make it occasionally. 😂 i can't find the video i was going to attach it to this answer. but my username came from when day6 guested at mbc's idol radio on 2019 (102819 to be exact). i remember sungjin and young k where having a conversation, i forgot the exact context. but young k said something like he was a tough cookie and sungjin said cookie ke. and young k repeated it. 😂 that's what i can recall since it's been so long ago. if i can find the video, i'll try to add it here. 😁 it was just so cute kaya i decided to make it my username. 🤣🫶 hope this answers your question!~
