Buffy: Don't! Don't say it. I'm going. [starts to go]
Spike: Oh, come on, we need to talk-
Buffy: We don't need to do anything, okay?! There is no "we"! Understand?
Unlike Cannot Spit It Out or Aborted Declaration of Love, this trope is when a declaration of love is cut off by something outside the character's control. Usually the audience will only hear the "I" while the "love you" is left unsaid. It might even be left unclear as to whether or not the statement even is a declaration of love at all.
The interruption might come from a Moment Killer. In more serious instances, it might come from the character losing consciousness or dying. If two characters have had a lot of UST then this can be a good way for writers to taunt the fans.
In some cases, the interruptor—especially if it's the target of the declaration—may cut them off with a knowing look or a declaration of their own, making the declaration unnecessary. Such is usually mind-numbingly heartwarming.
- This is Played for Laughs in Ah! My Goddess. Keiichi works up the nerve to finally confess his love to Belldandy. The moment was right, and the two were alone. Keiichi begins to speak the words... but then Skuld pops out of nowhere, right in front of Keiichi when he says "I love you." Keiichi is embarrassed that he said it to Skuld, and Skuld goes into a Heroic BSoD of sorts due to the shock that Keiichi confessed to her. Certainly it had to have been a mistake! Belldandy, however, knew that his words were directed at her, and was very happy to hear him confess his true feelings for her.
- In Attack on Titan, moments away from them being eaten by the same Titan who killed Eren's mother, Mikasa starts to confess her feelings to Eren and leans in to give him a Last Kiss, only for Eren to regain his fighting spirit and interrupt her.
- In Cardcaptor Sakura this seems to be what is happening with between Touya and Yukito with Nakuru constantly butting into the conversation on purpose at the exact point that it seems that confession is about to take place seemingly as she fancies Touya herself. It's actually somewhat more complicated Touya is actually trying to confess that he knows Yukito isn't human... AND that he loves him and wants to sacrifice his own magic powers to save Yukito's/Yue's life, but Nakuru/Ruby Moon wants to steal Touya's power before he can do so.
- Syaoran gets his fair share of them during the second half of the series. He tries in several episodes to tell Sakura that he likes her, only to get cut short by Kero, Yamazaki, and at one point even Sakura herself!
- City Hunter. When Ryo, due Mick's interloping, finally decided to declare his love to Kaori, the declaration was interrupted by Kaori accidentally blowing up the building.
- In Fairy Tail, Simon, Erza's childhood friend, is nearly killed while doing his declaration of love to her. They only see each other 8 years later.
- In the Japanese version of Fullmetal Alchemist, Edward cuts off Rose's confession mid-sentence because she isn't in the right mind at the time. The English dub has her finish the sentence.
- Hajime no Ippo: At first Ippo just Cannot Spit It Out, but during the Beach Episode, in a hotel room, at last he manages to say to Kumi, "I've always loved you!" Unfortunately he beats around the bush so much that Kumi has fallen asleep by the time he says it and she was a bit drunk too. So the declaration is "interrupted" by her not listening to it.
- Hana Yori Dango had this as a joke in one episode. When Domyouji tries to confess his love to Tsukushi the next day after he's saved her from freezing to death, the noise from a passing snow plow blares over his voice so she can't hear him. Then, when he tries spelling it out for her on a little electronic device instead, she happens to look up and see a shooting star that just happens to be zipping by overhead at that moment and misses his message.
- Irresponsible Captain Tylor:
- Harumi breaks down in tears after Captain Tylor is taken away as a captive by her Raalgon superior, saying that he showed her the meaning of a human heart, but part of her speech is drowned by the shuttle's engines, so we don't know if she was making a Love Confession as well. We only see Yuriko's startled expression (she was giving Harumi a Cooldown Hug at the time, so was close enough to hear what was said).
- Empress Azalyn falls for Tylor, but her Love Confession is interrupted by an attempted assassination via bomb. Azalyn accompanies the comatose Tylor aboard his vessel as a prisoner in order to finish telling him, though the usual comic shenanigans continue to get in the way.
- My Monster Secret:
- A flash-back where the protagonist Asahi was called on and rejected by the Class Rep before he even confessed. Remembering that, he quickly goes to confess to his new crush Youko... only to find out she's a vampire, and that her secret must not be revealed or she'll have to leave the school. Because of that, he ends up shelving his confession and asking her to become "friends". Asking her out in exchange for keeping her secret would have sounded a bit too much like blackmail after all.
- In chapter 47, Asahi is really about to confess this time, but Youko panics and cuts him with a Love You and Everybody reply, before running away. And that's after he had to deal with Aizawa's attempts to prevent him from getting to Youko in the first place.
- Ranma ½: Ranma Saotome pretty much makes it his mission to interrupt and shoot down all of Ryoga's attempts to confess to Akane. For hilarity, Ranma is usually in drag, acting like a girl, and just being a Manipulative Bastard in general.
- In Shakugan no Shana, Shana wins a costume contest and is told to give a speech. She attempts to use this to declare her love for Yuji, but Pheles suddenly attacks the event with a tornado.
- Steins;Gate episode 22 has Kurisu charging back into the lab to tell Okabe she also loves him, but he's already hit the button to begin another time leap.
- In To Love-Ru it's basically a Running Gag that something will happen whenever Rito or Haruna want to confess to each other. At least twice Haruna has been dragged off and replaced by someone else while Rito was trying to squeeze the words out. And they have been interrupted a couple more times. The first time it was Lala, which helped set everything up, although she did later realize he didn't mean her at the time. The second time Haruna was replaced by....most of his class.
- A much more tragic one in X1999. Maybe. Seishirou's last words to Subaru are "I ... you.." Seishirou being who he is, it's up in the air as to what he meant to say and if he was being genuine or simply mind gaming Subaru.
- In Yona of the Dawn, after Hak finally confesses his love of over 10 years to Yona, she tries to confess back in chapter 153. However, in an ironic twist, Hak is the one who interrupts her before she can. Even more ironic; he does so to explain that he doesn't expect her to return his affections and for her not to worry about it, and then walks off before she can try to tell him again.
- In Empowered, Mind is interrupted when he declares his love to Sistah Spooky, who arrives precisely "three seconds too late" to save her from burning up in a descending space station.

- Sin City. Nancy Callahan is about to tell John Hartigan she's fallen in love with him since he saved her life as a child, when the man in the car tailing them puts a bullet through the windscreen. After Hartigan disposes of the attacker she completes the confession in a hotel room, and even offers Rescue Sex (which Hartigan turns down on principle, as his love for her is of a surrogate daughter).
- From the New World. Saki begins declaring her love to Shun, but Shun interrupts her to tell her goodbye. He reciprocates her feelings, but he's about to make a Heroic Sacrifice and hearing a confession would make that harder to follow through.
- Podkayne of Mars. The title character says; "Do listen please, because this is important. I love—" before she is killed by an atomic blast. Her sociopathic brother wonders who it was she loved. "Everybody, maybe."
- Angel. After Amoral Attorney Lilah Morgan is killed, her lover Wesley has a Dead Person Conversation about their Dating Catwoman relationship.
Lilah: The only true thing I ever—
Wesley: You didn't love me! You couldn't.
Lilah: We'll never know now, will we?
- Buffy the Vampire Slayer. In "Crush" Spike is about to blurt out a Love Confession when Buffy cuts him off, shocked and disgusted that this amoral former enemy turned reluctant ally has fallen for her. To ensure he won't be interrupted a second time, Spike later zaps Buffy with a taser and chains her up in his crypt so she'll have to listen to his full spiel. Needless to say Buffy is not impressed by this either.

- Ross is constantly cut off through the first season when he finds the nerve to ask Rachel out. He never could find the right time because just as he wants to tell her, he's attacked by a cat that falls on him, or Rachel dates somebody else.

On the plus side, Simon's recurring Embarrassing Nickname of "Boner" has been passed onto Neil.
- Murdoch Mysteries: Late in "The Murdoch Sting", Murdoch literally goes down on one knee and tries to propose to Dr. Ogden. At first, he interrupts himself while trying to pop the question, but then she interrupts him to say, "I can't!" before fleeing into her house.

- The Professionals. Bodie and Doyle are driving a New Old Flame of their boss George Cowley to the airport after she's survived an assassination attempt, and she begins to say, "Tell George I..." before being drowned out by a police siren.

Poor Pendrell got shot a moment later and was rushed to hospital. He died off-screen in the next episode.

Ironically, for all the times he tried to tell her on purpose, he ends up telling her completely by accident.
- Final Fantasy IX has one of the funniest interruptions of love. Eiko lost her love letter to Zidane and it has been rolling around from hand to hand.
