Couples odd behavior or normal?

there’s this couple right not the neighbors by the way. the girl is named jane and the guy is named toby. toby used to like me years ago but jokily bullied me. everytime i’m in a class, both of them stare at me for the longest time. no specific stare but. oh by the way i’m not into him, but i think i might be into girl. there has been some times that i made eye contact with the guy toby on accident. and jane would notice. one time that happened, later that day she turned to me and smirked. not in a mean way tho, and he wasn’t around. there’s also some times where i feel odd like she’d agree with me a lot when there’s a class debate going on. there has been times where. i see them being cuddly in the hallway and he’ll stare at me the whole time. or other things like i wear a short shirt and they’ll both stare at me. i can’t tell if i’m overthinking things, they hate/judge me, or if it’s something else?
