It is easy to give a sensible explanation for not contacting someone. They are probably busy. The moment is not right. You will have more to say next week. In Uroko, Motohiro Hata gives that familiar hesitation a physical shape. The title means ‘Scales,’ as on a fish. Following that image makes the song more interesting than a general invitation to be brave: what protects the speaker from exposure may also be keeping him from the person he wants to reach.
The scales protect and conceal

The fish image near the beginning sits close to the speaker's self-consciousness and his excuses. Scales create a visible surface. They can be understood as a kind of covering between what is inside and what another person sees. In that reading, an explanation can be a way of presenting yourself while withholding the feeling that made the explanation necessary.
It would be too simple to call that covering cowardice. Not every hesitation is pointless, and rejection is a real possibility. A person may have learned to stay guarded for understandable reasons. The useful tension is between two costs: the risk of reaching out and the loneliness of never doing so. The metaphor allows protection to have a purpose without assuming that the purpose remains helpful forever.
Imagine drafting a message to someone you miss, then replacing it with a long account of how busy you have been. Both versions may contain true information. Only one makes your wish to reconnect easy to understand. Thinking about that difference can clarify the song's image without turning every quiet person into a puzzle to be solved. The reader's everyday example is separate from the events described in the lyric.
Summer puts pressure on an indefinite later

The season matters because it moves while the speaker hesitates. Summer's approach makes time feel less like an unlimited supply. I read that setting as pressure on the promise to act later, rather than a calendar from which we can reconstruct the characters' plans. The song does not need a detailed departure itinerary to make waiting feel costly.
There is a difference between choosing a considerate time and demanding a perfectly safe time. The first takes another person's circumstances into account. The second can quietly require a guarantee that they will respond exactly as you hope. A season cannot provide that guarantee; neither can an endlessly revised message. What it can do, as an image, is make the delay noticeable.
This is where a modest action becomes more useful than a dramatic imagined reunion. Asking whether someone would like to meet leaves them room to answer. Deciding that you already know what they think keeps the whole relationship inside your own speculation. That distinction helps keep the song's urgency from becoming pressure on its recipient. Wanting contact does not create an obligation for the other person to accept it.
Movement does not wait for certainty

The resolve in the chorus does not depend on every painful possibility having disappeared. That is what gives the image of shedding scales its force. Becoming less protected can be part of moving, rather than a reward available only after the world has become safe. The speaker's determination and his vulnerability can be present at the same time.
Literal fish biology is not especially helpful at this point. The song is using a body as an image for a human way of hiding. Treating it as a scientific proposition would answer a question the metaphor is not asking. Equally, turning it into a guaranteed happy ending would remove the uncertainty that makes the choice matter.
Try listening to the repeated resolve as a direction the speaker needs to remind himself of. Repetition can sound confident while still revealing how much reassurance is needed. On this reading, courage is not an extra layer of hardness added to the self. It is the willingness to make one intelligible, respectful move before knowing the result. That leaves the song's energy intact without pretending that longing alone can decide what another person will do.
A question for your next listen
Connect the early fish image to the returning idea of scales. Then ask whether the chorus promises a successful meeting or commits the speaker to moving towards one. The distinction lets the confidence and uncertainty remain audible together.
