I can't really recall the title nor the premise but I've written out the notes I CAN recall. I'm absolutely stunned I didn't favorite it and it's one I'd like to continue reading so if anyone can pinpoint it from this I'd be GRATEFUL

- Near positive it's a isekai, main character is a girl! I cannot recall if she's a villainess or is seeking to change a bad fate! I might be wrong but I think she had long black hair.

-Main character uses memory to find this like black market mage who has a large cat (like a tiger or leopard) that she tricks with catnip in her pocket. She then makes deals with him with money and other knowledge to get info and assistance!

-Mage guy is either a secret noble or royalty, this is shown pretty early on. I recall he has blonde hair as he normally is but when hiding as the black market mage he's dulled his hair and eyes and has eye bags. He uses different stamps depending on how favorable a deal is. He's big on money and making money, but he's not corrupt. Pretty sure he's the main male lead.

-It's definitely a romance, likely a comedy. She goes to the mage regarding his real persona asking why he's freaking her out at school. He then gets paid to look into himself.

-I recall some of the deals they made were weapons or how to move money using hidden space. Most vivid is she sets up essentially a starbucks by making a logo and a franchise and he's all for it.

-Later on I recall there is a clocktower scene, I think at the school. I cannot remember if it was hostile or loving.

I'm very sorry I know that's not much to go on. Please help though I've been scouring isekais for the last 2 days and I'm losing hope all together!!
