Hormones series (S1-S3) are the very first Nadao series I've watched and I like it so much because it fits my standard more than G*MMTV's shows i've watched before. After that I challenged myself to watch all Nadao shows and that's how I found this series. I actually watched the trailer before it aired but didn't really pay attention to it so I missed watching eps 1-3 in realtime. But, a day after eps 3 aired I suddenly have the urge to start watching it so yeah that's how I came to the Thai fandom :') I can't even explain in detail how amazing ITSAY is bcs it really impacted me that much. After watching ITSAY, I watched so many new shows (almost 20 new series + movies), but not even one lingers in my mind like ITSAY did...That's how powerful ITSAY is. Should watch this yourself bcs sometimes I'm really sorry for the ones who might missed this series.
