1. いつも迷惑ばかりかけるけど いつも散々困らせちゃうけど

Romaji: itsumo meiwaku bakari kakeru kedo / itsumo sanzan komarasechau kedo

Cultural Nuance: An honest confession of her awareness that her clumsiness and magical mishaps burden Morihito, mixed with an apology and a deep sense of trust in him.

🗣 Japanese Insight "Sanzan" (散々) is an adverb used to emphasize that a situation is terrible, disastrous, or "beyond help." It tells us that Nico’s magical accidents aren't just minor mistakes; they are "disastrous" uproars that involve everyone around her.

The ending "-chau" in "komarasechau" hints at her reflection on her actions, but also a sweet reliance on Morihito, knowing he will always be there to catch her.

2. 曖昧な言葉じゃ 真面目な君には 伝わらない

Romaji: aimai na kotoba ja majime na kimi ni wa tsutawaranai

Cultural Nuance: This line depicts the frustration of not being able to express her feelings directly, contrasted with Morihito’s personality—he is so earnest that he often fails to "read between the lines."

🗣 Japanese Insight "Aimai" (曖昧) refers to things being vague, unclear, or fuzzy. In Japanese communication, being indirect is often seen as a way to be polite, but for these two, it only causes a disconnect.

Because Morihito is so "Majime" (earnest/serious), he takes Nico’s words exactly as they are said. He struggles with "Gyōkan o yomu" (行間を読む), which literally means "to read between the lines." He fails to grasp the hidden emotions or the "true intent" tucked away behind her vague phrasing. This line perfectly captures the agonizing emotional distance caused by his honest yet blunt nature.

3. 頑丈なそのハートを覗（のぞ）いてみたい 融（と）かしてみたい そんな時こんな魔法はどうかな？

Romaji: ganjō na sono heart o nozoite mitai / tokashite mitai / sonna toki konna mahō wa dō kana?

Cultural Nuance: The desire to see his true heart (nozoite mitai) and to soften his stubbornness (tokashite mitai). It’s a witch’s unique approach to a romantic challenge.

🗣 Japanese Insight "Ganjō" (頑丈) describes buildings or bodies that are extremely sturdy and won't break easily. Here, it refers to Morihito’s "ironclad" logic and stoicism. Furthermore, Japanese has multiple ways to write the verb "Tokasu," each with a different nuance:

• 融かす (Tokasu): To turn a solid into liquid by adding heat (metal, snow, ice). This is used here to imagine Nico’s passion melting his frozen heart.

• 溶かす (Tokasu): To mix something into a liquid (like sugar or salt), or a general term for melting.

• 解かす (Tokasu): To untie, loosen, or comb through something (like a knot or hair).

The choice of 融かす emphasizes that her love is the "heat" that will jolt his sturdy heart into melting.

4. やっちゃえ せーの (Try, try, try) あやふやだって (いいの いいの)

Romaji: yacchae / sēno / ayafuya datte / iino iino

Cultural Nuance: A cheerful shout celebrating the importance of taking that first step with courage, even if you lack perfect confidence.

🗣 Japanese Insight "Yacchae" (やっちゃえ) is a powerful, positive word of encouragement meaning "Go for it!" or "Just do it!" It encourages someone to step forward on the path they believe in without fear.

"Sēno" (せーの) is a rhythmic shout used to synchronize timing when a group starts an action together.

"Ayafuya" (あやふや) refers to things being uncertain, vague, or unreliable. Nico acknowledges her actions might be "ayafuya" and shaky, but she shouts "Iino!" (It's okay!) and charges ahead anyway.

5. 溢（あふ）れる想いで空回（からまわ）り

Romaji: afureru omoi de karamawari

Cultural Nuance: Her overflowing feelings for him become uncontrollable, leading her efforts to backfire despite her best intentions.

🗣 Japanese Insight "Afureru" (溢れる) means to be so full that it spills over the container. It refers to a state of being so full it overflows.

"Karamawari" (空回り) refers to gears that are spinning fast but not meshing, meaning the energy is being wasted without moving forward.

No matter how powerful her magic is, her "internal steering wheel" of love keeps spinning in neutral. Nico’s magical skill and her clumsy romantic heart create a gap that is heartwarmingly adorable.

6. また君に くどくど言われちゃうけどほら こんな day by day がいい

Romaji: mata kimi ni kudokudo iwarechau kedo hora / konna day by day ga ii

Cultural Nuance: Even though getting lectured by Morihito is tiring, she sees it as proof that he is looking at her. She loves this noisy daily life exactly as it is.

🗣 Japanese Insight "Kudokudo" (くどくど) is an onomatopoeia describing someone repeating the same thing over and over in a tedious way (nagging). The expression "Iwarechau" (言われちゃう) is stronger than just "being told." It adds a nuance of "Oops, it happened again" or a slight sense of being troubled by an unwanted situation.

"Hora" (ほら) is an interjection used to get someone’s attention. Even while being scolded, Nico smiles and says, "Look, this lively, messy daily life is our happiness."

7. だからほら うだうだしてる場合じゃないの 掴（つか）め happy エンディング

Romaji: dakara hora udauda shiteru baai janai no / tsukame happy ending

Cultural Nuance: There’s no time to stand still and worry. This is an active declaration to seize the best possible outcome with their own hands.

🗣 Japanese Insight "Udauda" (うだうだ) describes a stagnant state where one talks aimlessly without reaching a conclusion or dwells gloomily on a problem.

Nico uses "Hora" to shake off that "udauda" stagnation. Instead of being toyed with by fate or prophecies of disaster, she decides to run toward a happy ending with her own feet. This short phrase encapsulates Nico’s fundamental energy.

🎤 Emotional Summary

YOASOBI’s "Watch me!" is a song of bonds, depicting how two people who were once lonely now build a vibrant "day by day" together. Whether she’s magic-failing in "Karamawari" or being scolded "Kudokudo," even those seemingly difficult moments are precious parts of Nico’s life with Morihito.

Just like the story Kokoro Kororon, where Morihito turned the handle of Nico’s heart, their destiny began to move that day. Nico, whose actions are "Ayafuya" but whose heart is true, and Morihito, with his "Ganjō" (sturdy) heart that supports her.

Her wish, "Keep watching me by my side forever," colors their daily lives more vividly than any spell ever could, and it will surely lead them to their own perfect "Happy Ending."
