So um I was wondering who is the uke and who is the seme from the pairing with Suho and Lay.

Please let me know your thoughts because I am in the process of planning an exo story and i need to know this. 

I am currently putting Suho as the uke and Lay as the seme.

So let me know your thoughts on this and if it is the other way.

[Because honestly they probably switch every now and than]
