The catch is that each subsequent person is less and less likely to say yes to you, and you might even get these kind of sad scenes where they start asking you if you still love them because they "saw you with so-and-so." I was under the impression you can date any person, at any LP level. You cannot break up, but if you wanted to you could have a harem. Since you're trying to date Kiel, I will guess and say you're a girl.Thing is, it becomes more difficult as you get to the next guy. If Forte isn't going to a dungeon with you, you may be invited to a Pajama sleep over. Now that I type it out it seems sort of mean, but I might end up marryin kiel, seeing as Doug has sworn us enemies. Look at the "Town Events" section in your diary to figure out who's involved in the event.It gets more and more likely that they'll accept the higher their LP, though; I tried asking someone at 9 once and he said no, but I asked a different guy at 10 and got a yes.So I usually bring forte and kiel with me to dungeons but now I realize tha was a bad idea since they are involved in a lot of events. Kind of annoying, but just keep talking to all the participants when they're in different places, and the event will eventually end.But no one else in my town is strong enough so I'm waiting until this event is over. Over the past week or so (in game), Forte has been asking me a lot about her brother readi books and how she wishes her father had stopped him and stuff like that. Kiel will come on adventures with me but Forte wont. I don't remember what the LP level you need to date someone is, but seven might be enough.The dating is kind of weird in this game in that you can't break up with anyone after you've asked them out and they've accepted, but you can start dating other people at the same time.
Once you marry one person, the others go back into Friend mode. Talk to her, and if she doesn't say anything about it there may be a Mini-Event with someone. For first lover, you have 30% chance to succeed with 7 LP, 60% with 8 LP and so on.
But, it won't work for your second, third, fourth, fifth and sixth. But for the third and fourth, you'll almost always need to get them to 8 LP for that 30% chance, and for fifth and sixth lover, you'll need at least 9 LP for the 30% accepting chance.
