Lyric

The phrase "a bouquet of flowers for a broken heart." Before this love began, there was a major heartbreak or a devastating event. It expresses how the "voice" reached the depressed heart, bringing color to the scenery, and how time, which had stopped, began to move again.

I'm afraid of getting hurt.

I want to tell myself I'm just being giddy.

I'm trying to control my feelings.

The strength of love is that it easily leaps over the "lid."

Even though my head tells me it's wrong, my heart craves you uncontrollablyan "uncontrollable state."

I block out the surrounding noise. My feelings for you are so strong that I can't see anything elsea "world just for the two of us."

I tried to lock away and protect my heart, but your voice and face burst through and pour in. "The pleasure of having my defenses breached."

The role of the season "summer." It's a somewhat forceful season. Because I can "blame it on the heat," summer functions as a stage for me to resolve "I won't go back" to my cowardly self.

Overall Summary
The existence that was initially just a "voice" transforms into "your face I want to keep looking at" by the end.
The way the emotional distance gradually shrinks is depicted like a gradient.
When the noisy heartbeat is accepted as "not unpleasant," it transforms from a mere premonition into certainty.
The composition is designed to create a sense of "acceleration" when set to melody.
This was utilized to its fullest potential.
