Initially, Shiryu was reluctant to take the medicine because he believes it wouldn't work. He changed his mind because even if the chances of working are small, it's worth taking that chance. Just so he can be with Seiya again...
Although I don't ship Seiya with any of the three girls(I headcanon him as gay), I think this interaction is very sweet.
Maybe Seiya is a bit self-aware on how emotional he gets over Shiryu's well being. 🤔
