I just feel like Luke would be the type to be super physical. Like, even if you were only friends he’d still have his arm around you all the time and hold your hand and stuff. He’d be the kind of guy that if he saw you somewhere he’d just hug you from behind and rest his head on your shoulder and say “Hello, beautiful” and you wouldn’t even have to differentiate his voice because you would already know it was him. He would be the kind of guy to grab your hand when you’re going through a dense crowd and then “forget” to let go later. He would be the kind of guy to listen to you talk about how bad your day was and kiss your forehead and hold you a little closer than is needed while hugging you, mumbling about how sorry he is and how much better tomorrow will be. He would be the kind of guy to make you think he was totally zoned out because you were boring him when really all he can think about is that one time when you accidentally kissed and now all that’s on his mind is how to get your lips on his one more time. Because Luke’s not like the media sees 5sos. He doesn’t go around just randomly sleeping with celebrities and fans. He has a massive heart, and he would be way more affectionate than people think. He would be genuine. He would be real. And he would prove to you every day that he loved you, even if you didn’t know what kind of love it was.
