Written for the prompt "What about Lysander X Armin?"
Their interests don't align much, or maybe at all. While Armin is totally supportive of Lysander's music, he just isn't as into it as he is. And as he's been told before in no uncertain terms, being good at Guitar Hero does not count as a musical ability.
Armin doesn't really pay attention to the fashion thing either. Sure he thinks Lysander's style is cool, but personally he doesn't really care about his own clothes. It's not like his opinions on clothing are taken seriously anyway, Lysander totally rejected his suggestion that a monocle would tie his look together.
Lysander isn't a gamer at all and Armin suspects that even something as simple and well-known as bejeweled would be unfamiliar to him. What kind of deprived childhood did he have anyway ? He spent his days outdoors like they did in the olden days. God, they have nothing in common, but Armin is determined to find something for them to bond over.
Armin searches through his old games, hoping to find something Lysander might enjoy and have the required skill level to play. It has to be something for an outdated console, because Armin will have to give that away along with the game. After a considerable amount of time spent searching and a great deal of thought, Armin finds the perfect game.
When Lysander wakes up the next morning, there's a package waiting for him at the door, with a handwritten note reading "Don't call me until you've paid off your first mortgage."
The note is deliberately phrased to provoke a reaction and it works, because Lysander immediately opens the box and begins a five hour Animal Crossing binge.
The game doesn't seem to have any overarching objective, in the short term you fish, collect furniture and pay off your debt, and the long term seems to be a continuation of that path. It strikes Lysander that the game should be boring, he's basically continuing life on a small screen, yet he's hopelessly addicted.
He does pay off that first mortgage eventually, even if it probably took much longer than it should have given how many bells he spent perfecting his miniature self's style and the look of his home. Though to be fair, he did make it harder on himself by donating so many fossils to the museum. Selling them on could have made a significant dent in his debt.
Armin said not to call him until the mortgage was paid, but Lysander, so engrossed in the game, lets it slip his mind.
Armin may come to regret his gift.
