Enlighten me please

Sort of? I mean the seme is pretty possesive and when you've been reading BL as long as i have it's pretty obvious who ends up topping. But, it looks like it could go either way at first, and even the uke seems surprised at the end as he was expecting to top (seme is very sweet and soft). The sex scene is pretty short tbh and i just really love this story

Thanks so much!
