Shii handled the situation well tbh. He got him out if his comfort zone and pushed him to something he never thought he would get into which is his sexual feelings. Shii didn't force it per say. I wouldn't know what to do if I felt like Shii so he did decent rather then raping him. In my opinion that's not rape there was consent on both ends.
Everytime I read the "BOOM" sound effect in any manga I just think of earape sounds ╥﹏╥
