Yes, there is. It's seme x uke.
It's just like shipping a boy and a girl, the boy's name comes first. Hence, the seme and that's why there are some friends who fights over shippings like this because the arrangements on names when shipping indicates the roles
Seme x Uke. I think it has always been like that since long time ago. Example: Ruhana Slumdunk doujinshi by Ayano Yamane (Full Speed and Come with the wind) has ‘Rukawa x Hanamichi’ written on the cover, Hanamichi being the uke. I think the proper placement is more important for those reading fics or doujinshi since one might prefer the other to be seme or vice versa. Like SasuNaru vs NaruSasu (Naruto fandom).
How's the proper shipping?? Seme x Uke or Uke x Seme?? It's just that I'm not sure if I'm doing it right..
