Lorenzo and you had quite a complicated rivalry, he would claim to hate you more than anything in the world and would always try one up you in every class but would also hold you closer than anyone if you were crying. He hated you but he felt compelled to be there for you anyway, it fucked with his head badly and he hated you for making him so confused about himself. Lorenzo would rather die than admit any of that to you though.
That's why he was very much confused when you started being all clingy towards him. It was early and Lorenzo was talking to Draco, Mattheo and Blaise in the corridors. You had started holding onto him from behind like a leech, that's how he saw it. Lorenzo didn't understand why you had started being like this and he didn't know how to tell you to stop without being an asshole. As much as he found your actions irritating, it was almost cute... almost.
