Don't save sc chats? 🤔🤔🤔

The guy I'm talking to on sc told me "don't save the chats btw"

Sounds very suspicious to me.. should I take it as a red flag or am I overthinking? I mean, for what reasons would he not want me to save our chat that is on MY phone, he can unsave it from his but from mine? I feel like he has another chick around & probably doesn't want me to screenshot if anything were to happen.

Which btw, I wouldn't be talking to him if he did have a girl so this makes me suspicious of him.

(P.s. I know him in person, he's a freshman in college, I'm a junior in high school, I met him when I was a sophomore & he was a senior at my school)
