Spoiler!
He is now just a child like 15-16 in novel so he has to grow but now elf give him curse so his growth would stop.but he would lift his curse then he would get his growth eventually and become as tall and muscular as he was in past. Then he would try to top him but he couldn't because he would'nt feel its good. so still he would remain bottom.
