Their strange friendship had grown from Draco writing to ask for his professional opinion as a potions master, to them enjoying a drink in Hogsmeade occasionally, to Severus visiting every other Friday afternoon during the school holidays. Draco gained the distinct impression that Severus wasn’t quite sure how he felt about their friendship either. Draco had found just not talking about it to be the best solution though. He couldn’t even imagine Severus discussing his feelings - he’d probably never come back again.
