I haven't seen any harem but he has vaguely become aware of someone, not sure if it will lead anywhere though. Romance isn't on most of these characters minds. At least not yet.
He's not romantically involved with anyone as of yet, but there is a girl close to him but only as a subordinate. Nothing resembling any type of blossoming romance.
The smut deserve standing ovulation or something ToT. Camping here (◕દ◕)
