Guy Becomes Instant Legend With His Sweet Reaction To His Fiancée's 'Cheating' TikTok Prank

A woman attempted to fool her fiancé into thinking she was about to cheat on him through a popular social media-geared "cheating" prank.

But her mischievous plan backfired and the internet swooned over the boyfriend's adorable and innocent response. He became an instant internet icon.

Sam and Monica are social media influencers with a TikTok page highlighting their romantic lives together. They currently have 1.2 million followers on the popular app.

The prank involves someone texting the other person implying they are cheating on their significant other and then filming their reaction.

Here is Monica's attempt at the prank:

In the clip, Sam left their home to go to his car.

Monica texted Sam under the guise he was the "other person" and wrote:

"He's leaving now, you can come over."

Sam then immediately ran upstairs to confront her about the text, but not with the reaction you would expect.

He stood in the doorway with a grin on his face, prompting Monica to ask:

"I thought you were leaving?

Sam, missing the joke completely, giggled while saying:

"Yeah, I was leaving, until I saw your cheeky text message."

"Are you planning a belated birthday surprise for me or something?"

Still determined to keep up with the ruse, Monica said:

"No! Your birthday was over a month ago!"

Sam remained giddy but tried not to further spoil the "surprise" she was planning for him.

He responded:

"Yeah but it's never too late to celebrate, is it? I know you're doing it, OK, I love you so much."

He kissed her and went on his merry way after pledging:

"I'll act surprised, I promise."

One of the hashtags on the video was #couplegoals. Indeed.

The adorable clip—which was captioned, "Now I need to throw him a party"—received over 605.9K likes.

Followers gushed over their sweet relationship.

Monica may have failed at the prank, but she has already found a winner in Sam.

Hopefully, she isn't having any problems planning that fabulous "surprise" party for her irresistible Romeo.
