Dropped off at chapter 27. Romance starts at chapter 3 to a 'young girl'! MC is 18 btw. There is relationship between side characters and they are 18 and 14! No actual harem so far. Unfortunately MC basically forgives the hero party for their abuse towards him. The only thing saving this comic is the action and 'cheat' aspect. So if you can deal with it the immature romance cliché then go ahead
