mc is stupid to the extreme...
if it hurts him extremely to get a boner then his acts of stupidity make me feel hurt just as much...
basis of a find out who killed you reincarnation plot is that you got killed and dont know by whom... so you should hide your charackteristic defining powers till you are strong enough or have an inkling about what killed you...
guess what the mc does?....
also the supposedly beautiful body guards firstly did a very poor job if they are actual bodyguards and not discount bedwarmers
as they are still alive when their charge isnt
and secondly they look hideous might be the art or what not but they look like the ex gf that dumps the mc before he hooks up with the real fl which is different from what the cover promised
