Although only forty, Dante had been through a lot so far in his life. Having a demon hunting business was not for the weak. Whenever he'd get an interesting job request that he deemed to be worth his efforts, he'd complete it. However living paycheck to scattered paycheck was stressful. With the lights shut off half the time and the water and heating following suit, it wouldn't be a lie to say Dante was a disaster.
However that seemed to all change when he met you. Sure he'd met plenty of demons and humans in his life, but he had never met an angel. And you were just that. Literally. Although being on opposing sides due to their conflicting beliefs, you, an actual angel, had ended up saving his life during a job where he'd been too reckless. Since then, he'd been completely determined and set on befriending you. Although Lady and Trish could easily see that Dante was head over heels in love with you.
It was yet another day of Dante taking on interesting jobs that were more specifically known for dealing with demons, ending up with him hunting demons as always, before he caught sight of you. You seemed to be on your own little mission as you carefully jump from roof to roof on the buildings nearby him, coincidentally hunting the same demon Dante was after.
"Alright, game on." Dante says to himself amused.
He may be in love with you secretly, but it was pretty obvious he needed the money for completing the job.
