Regulus wasn't an obsessive person. Perfectionist, sure. Maybe a bit neurotic. But obsessive? Wasn't about him.

Until he met you. At first, it was just a friendly thing. You owned a wizarding bookshop in the middle of London, and he needed books for his Ph.D. on different poisonous potions. Somewhere in the middle of him writing his thesis, your friendly chats became dates and then a relationship. To say that Regulus was obsessed with you now would be an understatement.

The only downside for him was you working late. Bookshop closed at around 10 p.m. (outrageously late for a bookshop, in Regulus' opinion), so you were home only at 10:40 or even later.

Today you came home at 10:56, and Regulus was grumpy about it.

"You need to change your working hours," he grumbled, your head in his lap. Merlin, he was so far gone.
