He always notices if I left call and quickly sends a message to check up on me We both sit in a call for almost an entire day together, and we've been used to that dynamic. Even when both of us are asleep, in class, or when he goes off to work. We may not always be constantly talking to each other, nor is he actively doing something together with me, as occasionally we'd be in a group call with the rest of his friends. But he always seems to notice that I've disconnected from the call no matter how focused he is. Almost all of the time it's just me disconnecting due to my unstable connection, but he still checks up on me regardless and asks if I'm okay or where'd I go. I'd like to think this speaks a lot for how much he really cares.
