Search Results: ways to cheer him up

I asked this a month ago:
In a camp, I met a guy who's my senior who took part in the planning of the camp (Let's just call this guy 'A'). His friends started shipping me and 'A' during the camp. 'A' is, to some extent, a friend. If I had a question, I would be fine with approaching him for help. It's easy for me to communicate with him. But everytime his friends are around, they tease him and me and he starts to laugh and smile. I joined a dance group for a competition, representing my specialized school against others (SoE vs FMS, both schools from the same polytechnic). He came to support, but I'm not sure if he came to support me, or to just cheer on our school (SoE). Thing is, very few people get to come along to support. (only 3-4 people from our course) He also starts conversations randomly before suddenly pretending I don't exist and playing with his friends. For example, earlier today, he wished me luck as I'm emceeing for an event later with one of his classmates. Last of all, my friend who claims to be very good at analyzing body language, says that everytime 'A' sees me, he tenses up; which apparently is a sign that he likes me? I don't know how to read all of this, and I'm afraid of overthinking and then reading into something that doesn't exist.

A month later and I can safely say that I am friends with this guy. There's stuff I've shared with him that I don't share to most. Occasionally we meet on the way to school as we take the shuttle bus from the same interchange. A few days ago, we met in the shuttle bus and when he saw me, he had this really cute shy smile and then sat next to me. We were talking all the way to school even though he planned to sleep on the way to school. We don't talk a lot on text, even when I try to put effort into keeping the conversation going. This makes me a bit confused: if I was his crush, wouldn't he try to talk to me even on text? We both have a lot of common interests.
