Am I overthinking? 🙂

Okay so m a 2nd year student (F) nd there’s a senior of 4th yr (diff department) who has been noticing me since I joined college..but we’ve never talked!!so today during lunch,, me nd my friends were sitting in the canteen nd sharing food like usual nd I noticed him standing near the entry nd pointing his phone towards our table like he was clicking something.. then when I hid behind my friend , I saw he went outside nd did the same thing frm the window nd then later he came nd sat at the table directly in front of ours. Then he walked past my table pretending to be on a call but his phone camera was facing me nd it genuinely felt like he was recording me nd ig there's a pattern nd it didn't feel accidental

Am I overthinking this?
