Is he being really friendly or is it a genuine connection?

For context, I live on residence in university and this boy lives on my floor. I first invited him to dinner and skating with my friends, but we ended up skating alone together and talked about hobbies, interests, and more personal information.
The next day, we had dinner again and then walked around aimlessly around the city until like 2 am, talking. In my mind, he told me some very private information that usually wouldn't be told to someone he has known for only 2 days. He also gave me his sweater in the process and I had no rush in returning it.

One of the things he told me that I was the first person to introduce myself to him first and that he was glad I invited him to dinner.

We began to frequently have multiple walks until 2 am until he told me he did this with his friends often. He told me he was a people-pleaser and did anything for them. I was pretty stumped in realizing that this was a common occurence for him because it felt really special to me. As he grew closer to my friend group, he would be really friendly to them as well and I felt that our connection wasn't really that special in the end. He has also told me that he's had a girl mistaken his friendliness as a sign of affection, ultimately leading to a heartbreak. After all, if it were to be one of my friends who had introduced themselves first, he might've as well chosen to walk with them until 2am and gave them his sweater.

However yesterday, my friends and I would dm him separately and I realized that he would only respond and give updates to me and not them. I usually wake up with a text from him to take breaks or to sleep more, and he voice messages me while driving as well haha. However my friends told me that he was usually the type to never respond to their texts so I am a little bit confused.

I feel that I should just keep it as a sign of genuine friendliness and maybe wait for a confession if he actually feels anything otherwise. Guys and Girls what do you think of our connection?
