Welcome home's manga / #Full Color BL(5)

I cannot wait to see 3hat this BL has in store for us. I mean it was made by mingwa, The person who created Bj Alex? So this has to be great. Already seeing from the 1st chapter, seme is seemingly to be 'Toxic'.

I think the guy with the black hair is seme. Cause I'm reading the tags. But if he's not then, he must be a dominate sub? Or this entire thing is simply just seke. Or I'm wrong about everything and the blonde hair guy. Is just a top, but just whiney as hell.
