2. And if you thought that was sweet, here's Dylan hanging out with man's best friend — aka one the dogs who played Boy in Love and Monsters.

3. Plus, here's Dylan's precious reaction to the adorable video shared by director Michael Matthews.

The serotonin that Dylan's smile gives me is unparalleled. 🥺

15. When Dylan posted this sweet tribute to Teen Wolf — a show where many of us first fell in love with him and his acting — on its 10-year anniversary.

10 years ago today a werewolf show premiered on MTV and succeeded. Go fuckin’ figure. Love ya always Teen Wolf ❤️❤️❤️ #10YearsOfTeenWolf

Stiles Stilinski will forever have my heart. 💖

16. When Tyler Posey, who played Scott McCall in Teen Wolf, opened up about the bond he shares with Dylan, which started all the way back when they were auditioning for the show.

17. When Dylan outed himself as a massive Swiftie and praised Taylor for her incredible songwriting abilities.

it's official: @dylanobrien confirmed swiftie + harrie 💖

To be fair, Dylan's always been a Swiftie and a loyal supporter of Taylor. It was just super sweet that he got to talk about his love for Folklore, as well as his favourite Taylor songs, during an interview with Coup De Main Magazine earlier this year. In it, he gushed over "Mirrorball", as well as "My Tears Ricochet", "Mad Woman", "Epiphany" and "The 1". He's also a huge fan of Harry Styles. Somebody has taste!

18. When he starred alongside Sadie Sink (of Stranger Things fame) in All Too Well: The Short Film — which had us all feeling a million and one different emotions.

19. When he changed his name on Twitter to "Dylan O'Brien (Taylor's Version)" because he's a supportive bestie and stan like the rest of us.

20. When Dylan tried his hand out at viral TikTok dances — and absolutely nailed it.

LOOK AT THAT LEG MOVEMENT!

21. And I couldn't not include this TikTok because Dylan looks so damn happy dancing in it.

22. When Dylan looked incredibly handsome at the premiere of All Too Well (The Short Film).

23. And forever the humble actor, Dylan revealed that he was shocked Taylor even knew who he was — let alone offered him a role for All Too Well (The Short Film).

24. Meanwhile, here's Taylor singing Dylan's praises while on The Late Night With Seth Meyers.

25. When Dylan guest-starred on the Emmy and Golden Globe-winning comedy series Curb Your Enthusiasm as a more Hollywood version of himself.

26. When Dylan profoundly reflected on his career, film choices and the support circle he's had since being injured on the set of Maze Runner.

27. And finally, when Dylan posed with his puppy Tony and melted everyone's hearts.
