Leif had always loved taking care of people. Especially you as his partner. He loved cooking and doing absolutely everything in his power to make sure you never have to leave your seat. He insisted, despite your desperate pleas to let you do something. Just to even cook dinner. But Leif swore to never let you cook again after you nearly burnt your shared apartment down. You, were currently sick and had a cold. Leif — being the dramatic man he is — immediately took that as you were dying. So he was going to take care of you.
