What got you into Oh My Girl?
Short version: SSFWL and Banana Allergy Monkey.
Long version since I'm bored so buckle in for Storytime with Senpai:
I entered Kpop as mostly a Boy Group stan, except SNSD/Kara. Other girl groups I'd only watch casually, not bother to learn the members. Anyway, around 2016-17 I took a Kpop hiatus so I missed BTS rise, Twice, GFriend's rise, IOI, BP debut, all that fun stuff.
When I came back my fav group BigBang was inactive so I started looking for a new group to invest in, started with BTS and Blackpink but that didn't work out. And then I found Twice, and for a long time I was a happy Once (still am), with Twice as my eternal queens and also looking into other girl groups.
Slowly, I started getting more into mid tier and smaller groups, for the most part I found them more willing to experiment with their music, take risks, not have to follow the conventional trends and see stans eat it up etc. During this time, I discovered Secret Garden and thought okay, but not my type. But then Banana Allergy Monkey happened and it reminded me of Orange Caramel so I was intrigued.
Fast forward a year later, by now I've listened to stuff like Closer (loved it, top 3 Kpop songs), Windy Day, Cupid (amazing debut), so I know Oh My Girl are talented. But then SSFWL drops and oh my god, the outfits, the vocals, the live stages

I even ventured into OMG varieties and found the girls super adorable, I discovered Candy Leader Hyojung and variety queen Seunghee plus multitalented queen Yooa. And suddenly I started listening to their B sides, all their titles, even Secret Garden became a mega bop for me lol.
So I made the jump and embraced the Miracle Life, and slowly they transitioned into being my ults
Twice slipped to number 3 btw, Loona is 2nd now lol.
