Do you think me might like me?

I've been going to the gym a few years . Never really payed much attention to any of PT fitness instructor that much always done my own thing had PTs before. Since this covid outbreak we now have to book sessions in advance for the gym. The PT/instructor check the names. Theres this particular PT never spoke to until now. I'm not his client. He was checking the names after couple days in a row he was like "no no don't tell me" tried to guess got it rig I was just like "you remembered. I listening standing near to see if he did it to others behind me or overhearing in front he didn't. Hadn't seen him in a week and as soon as he saw me like said surname in enthusiastic way. All of the PTs do the checking names none of them act like that or like try to remember the name always ask. Yesterday in the morning on way to shop I saw him across the road as I was coming out where I live I think he looked over. I avoided looking it was too early. Later on I went gym he was training a client somewhere in line of sight was there before him. Caught few glances not too much as he was busy and I was focused on what I was doing. After I'd finished training as leaving down the stairs he was coming up he was like how are you smiling i said hiya back. None of the other PTs/instructors are like this with me or don't even say hello. Getting a feeling he may be attracted to me or he's being extra friendlier.
