I like Love 119 because it makes my heart flutter.

I really like it because it feels fresh and heart-fluttering, like first love.
The melody that starts gently blends well with the members' emotional vocals.
It is also interesting that you likened the feeling of having a complicated mind because of someone you like to 119.
It has a warm yet slightly wistful atmosphere, so it is a song that goes especially well with winter.
If you like Rise's youthful vibe, this is a song I highly recommend.
