An S/O that still goes to college? For anyone you want?
Oki!! Gonna start doing only 3 cuz' I can go into depth!
If you still resided in the human world than you would not be let on about her "profession." She would do everything she could to keep it from you.
Assuming you somehow did find out, she would ask you how much college meant to you, and try to keep you a secret from Slender from this point forward, ONLY if she feels she can trust you.
If she couldn't trust you, she'd take you to have your memory wiped forever, and try to get rid of any memory of you if she could
She doesn't fall for anyone easily, so if she fell for you then she wouldn't let you go if it were her choice. If you let her choose, she'll have you taken to the mansion(or her home depending on the au) and have you live there with her.
If you don't want to go and she can trust you, you can bet your ass that she's watching you constantly, making sure you don't tell.
Into actual college stuff, she would make sure you're taken care of and don't live off of Instant Ramen. She would come to your dorm room or home with food to eat and some stuff you can keep for later.
Since she didn't actually get to go to college herself she may ask you about what it's like or how you are.
Around finals she'd bring you stress food and coffee while making sure you're eating and sleeping before your big exams.
May buy you a skateboard or something of the like to travel around campus quickly.
She'll help you with textbooks though I doubt you want to know where the money comes from
She'll take care of you for sure, but she won't be super willing to let her s/o know quite how much she cares about them.
Having been a college student himself, he knows how stressful it can be. After going through all of the rules Clockwork had to go through before allowing you to continue on, he would help you in any way he could to let you be less stressed.
He would guide you through some meditation techniques he does and some teas that he's heard are good for stress.
He might collect some textbooks for you while completely avoiding the subject of where they came from.
Would make sure you eat a non college student diet because that's never good for you. May even bring some leftovers from Slender's cooking.
He'd make sure that you don't spend all of your time studying and go outside every once in awhile. He knows how it is when you stay inside forever.
He would give you the hugs you need after exams if you asked, even though he's not that physically affectionate in most cases.
If you need reassuring words he'll try his best, even though he's kind if worried about being found as cheesy.
He's not very comfortable with walking onto college campuses because he's worried about being found out in security so you'll have to meet him in town.
He'll take you off to a cute little ice cream shop and buy you anything you want. He won't eat anything himself because it will make him sick but he just enjoys seeing you happy.
Toby doesn't really understand being a student in a college like setting but he'll try to help you in anyway he can.
He will shower you in any cuddles and affection you need or want and try to help you get anything you want
He looks human enough to go onto your campus without gaining any suspicion so he'll often come you before long classes to bring you some coffee and breakfast, especially if he knows you won't get it yourself.
When he can tell you need to get out he'll take you on a walk through the forest and have a picnic with you in a clearing next to a creek. Maybe you can splash around in the creek after eating your favorite food and some pastries.
He will make sure you take care of yourself
