Spoiler for Light Novels, your answer:
As far as I know, yes. That's why I root for the Nina X Layfon relationship in the end of novels. Hardly any anime/manga has a story where the lead loves a girl, kisses her and the feeling is mutual but he ends up with somone other...I know I am evil by being way.
But well, Layfon's feelings isn't clear at all so perhaps the Leerin X Layfon isn't canon.
