Earlier, TaeTiSeo made their debut on M!countdown with their performances of ‘Baby Steps’ and ‘Twinkle’. Their perfect adlibs during both performances along with fanchants in the background left many who were watching with goosebumps.

I, for one, couldn’t help but squeal at their cute choreography and the fact that #TwinklingTTS was trending 1st worldwide while the girls were performing thanks to the power of SONEs.
