U&I (#23『放课后!』Mix)

The speaker misses someone who is usually close and helpful. Without them, ordinary things feel difficult, from cooking to knowing what to do. At first, the speaker focuses on wanting the person to return; then they realize they had taken their kindness for granted. The feeling develops into gratitude, which they try to express through a song.

Everyday details make the absence feel personal: the speaker wants the other person’s cooking and voice, and cannot remember where the sugar and soy sauce are. These small examples suggest not only practical dependence but also the comfort of shared routines. “Rainy days and sunny days” implies that the person has stayed beside the speaker through different circumstances. The song becomes a way to send words that feel hard to say directly.

The lyrics may describe a temporary separation, but they do not explain why the person is away, so a more serious absence is also possible. The speaker admits both affection and regret: they have relied on the other person without giving enough in return. Their uncertainty about whether “thank you” will reach the person keeps the ending tender rather than fully resolved. Still, singing becomes an earnest attempt to show that the relationship matters.
