Does he like me back?

I have a crush on a guy. I came to his country to study three months ago, and that's how I met this guy.

We have hung out together for several times. Most of the time he takes the initiative to invite me, but we didn't explicitly call it a date. When we meet at school, we often chat for more than half an hour and eat snacks together (but not a real lunch or dinner).

I feel our interactions are very pleasant, but I am confused about whether he likes me back or wants to take things further, for the following reasons:

1. He says he is very busy because he has to work to pay his own bills of living expenses, and he needs to handle work and study at the same time. There were times when I take the initiative to invite him out, he would use this as a reason to turn me down, and he replies messages very slowly online.

If it were me, no matter how busy I am, I would make time for someone I like and reply to their messages promptly, even if it meant sacrificing my sleep to catch up on work and studies. So I take his behavior as a sign that he may not be that into me.

2. Although during our chats, he tell me about a lot about himself, such as his family and his past. People from this country are generally talkative, so it's hard for me to tell if he is just being nice.

3. He seems too busy at the moment and doesn't seem to have the time for a relationship. He also strikes me as someone who takes emotions and relationships seriously, so I don't know if he would be open to a short-term relationship.

4. I am not sure if I am his type. I am Asian and he's a white guy, and he mentioned he hasn't had many Asian female friends before. Though I am considered attractive in Asia (I know this may sound narcissistic), I am unsure if it is the type that white guys would generally go for.

I enjoy our conversations and feel physically attracted to him.

At present, I really want to be with him, even if it's just a short-term thing (I am not looking for long-term either, as I won't be staying in this country for more than three years, which he is aware of).

My question is, does this guy like me (given that we have had deep conversations and one-on-one hangouts), or does he just see me as a friend? If I want to pursue a short-term relationship with him, is there a chance, and what should I do?
