Kagamine Rin, frustrated with Len's excuses for not picking up the phone, threatens to call Putin on him if he messes up again. Wanting to go together with him, she asks him not to leave her alone. Len then makes an appearance, noting how Rin, dancing to the music, was someone who fought alongside him in Russia. He notes several wrestling moves and Rin going on a rampage before Rin again sings for him not to leave her alone. She then gives a goodnight, only to later on begin begging to not be left alone in rapid succession.
- 『出たくない メンドクサイの！』 I don't wanna answer, it's really tiresome!
- 『分かるでしょ？ プーチン呼ぶわ！』 You got it? I'll call Putin!
- 『フラフラしてないで！』 Don't stagger!
- 『今日だけは 二人でサンデー！』 Just for today, it's our Sunday!
- 『ヒトリニシナイデ』 Don't leave me alone
Sound Effect AnalysisEdit
The three musical breaks in the song--the start, the middle, and end--are punctuated with the "RAN RAN RUU" clip taken from Ronald McDonald's Japanese ad campaign. Ronald McDonald's significance to Rin and Len appears to be antagonistic, resulting in Rin trying to kill him by Under the Cherry Blossoms☆, and may symbolize his interfering in their relationship.
- This song is the first appearance of Ronald's "RAN RAN RUU".
- This song is the first mention of Rin's iconic lines "Don't leave me alone," "Don't stagger," and "Just for today, it's our Sunday".
- Len's phrase "shall we do it?" is the signature phrase of the yaoi character Abe-san, who later becomes Len's lover.
- Several of Len's lines refer to pro-wrestling, such as moves like Cobra Twist and Rolling Elbow; similarly, a "three count victory" refers to a wrestler winning if the opponent is down until the count of three.
- Although Len is present in the song, only Rin is credited in the song title. Putin-P stated that the reason for that is because "Don't Leave me Alone." is "Rin's" song.
- The full version of the song, with the extra copyrighted audio removed, was released on Putin-P's first album, Don't Leave Me Alone.
- Len speaks about their time in Russia despite the two of them not getting their memories back yet; given that he appears to mistakenly believe he was a human soldier with her at the time, it's possibly the Vocaloids are aware of their past lives without knowing the actual details.
- Only in this song, Len's subtitle color in this song is dark blue. In "Let's Dream." it becomes light blue; similar to Camui Gackpo's in "The Broken Mirror.", possibly lending credence to his mistaken presumption.
