@Question2 and im saying so far no, he had a girlfriend and she didn't join him in his travel, she said she would catch up with him later, read the manhua.
@Question2 not realy close, because here has been times where the mc could have started a harem or had 18+ things but didnt, however, he does have semi op powers from the start. All the girls are like him however, he has not pursued anyone yet.
