Are these signs of a possible crus?


So I'm completing an internship, and my co-worker was hired a month after me, so we officially met on the first week of December and hit it off, from the beginning, in terms of conversation flow and being able to relate to each other as the youngest individuals in the office.
I always kept a friendly demeanour with him, but hence we are on opposite sides of the office, and he always walks over to my end to speak with me and check in; further, he chats with me from morning to afternoon via messenger and we also did exchange number in case we had to discuss work absences and so forth.
Furthermore, I do not drive to work; we made a deal that I would give him weekly gas money for dropping me home after work, so that has worked out for us. He compliments my clothes and so forth weekly and recently told me he would miss me when I left early for the dentist.
I did help him create a hinge account to find a girlfriend; yesterday, he mentioned that if he has ever said something to make me feel uncomfortable, I should tell him, as he would never do that on purpose.
We have a pretty friendly banter, and my manager has even pointed out to me that we have a good working relationship, but it has crossed my mind if he has a slight crush on me. Lol, he also mentioned that we have a good relationship.
He is 27. I'm 26.
