One Direction released their new single "Perfect" on Thursday night, and it didn't take long before everyone realized the song is a pretty obvious ode to Harry Styles' ex Taylor Swift.

On Swift's last album 1989, many songs are believed to have been about her relationship with Styles, most notably "Style" and "Out of the Woods." Styles was also allegedly the inspiration for "I Knew You Were Trouble" off her Red album.

Is next year's "break" the beginning of the end for One Direction?

"Perfect," which was written by a team that included Styles and bandmate Louis Tomlinson, seems to be a direct response to those Swift songs. Here's a rundown of the most crucial evidence:

"Perfect" lyric: If you like midnight drives with the windows down
"Style" lyric: Midnight, you come and pick me up no headlights

"Perfect" lyric: If you like to do the things you know that we shouldn't do
"I Knew You Were Trouble" lyric: And I realize the blame is on me / 'Cause I knew you were trouble when you walked in

"Perfect" lyric: But that don't mean that we can't live here in the moment / 'Cause I can be the one you love from time to time
"Style" lyric: It's been a while since I have even heard from you / I should just tell you to leave 'cause I / Know exactly where it leads but I / Watch it go round and round each time

"Perfect" lyric: And if you like cameras flashing every time we got out / And if you're looking for someone to write your breakup songs about / Baby, I'm perfect
"Style," "Out of the Woods" and "I Knew You Were Trouble": Every single lyric in every single one of those songs

Taylor Swift makes it abundantly clear hew new music video is about Harry Styles

The most damning piece of evidence? "Perfect" was even seemingly written to sound like "Style." Check out the mind-blowing mash-up of the choruses below:
