I like that 'I like' is honest.

It is a song that makes your heart flutter even more because it contains the emotion of honestly conveying your feelings to someone you like.
The members' emotional vocals blend well with the soft band sound, making it sound comfortable.
The lyrics feel like they are directly conveying that you like someone, so listening to them makes my heart flutter for no reason.
The flow, starting calmly and building emotion towards the end, is also really charming.
If you like warm yet heart-fluttering DAY6 songs, I would like to recommend this.
