He walked with me today HELLOOOO!???

Today when class ended I grabbed my coat and made my way outside, and walked past him and his friendgroup, he suddenly said to his friends 'guys im going, see yall tomorrow!', the EXACT moment I walked by.

Then he freaking walked behind me, and I FELT HIS PRESENCE. There were some bikes passing as I was walking and I stopped, I then flinched since he was so close, and I said: 'Damn, you scared me'. He then chuckled and said, 'Well if you're walking, you'd expect people to be behind you right?'. We then walked together to our bikes, they were coincidentally parked close to eachother. After that, he complimented how well I did at my presentation that day. I was so shy brooooooo.
