muichiro and tanjiro are currently at a hot spring, relaxing in it together. they are both dating but they haven't done anything like 'that' except for making out, but they have only done that twice. other than that, they haven't really done anything like that. they just usually do the cute couple stuff like, holding hands, hugging, kissing, and relaxing in the hot spring together. it has been a long day anyway, especially since they just went on a mission together.
