Aurinne created a topic of Koori no Jouheki

Does anybody know if this is one of those stories with the main characters all having messy love relationships (love triangles/squares and so forth)? The other manga by this creator is lovely, so I'm hoping not, but I'd like to know in advance because I don't enjoy those messy love dramas. (I don't need to know actual spoilers of who ends up with who or anything, just generally is it straightforward 1 x 1 or not. ) Thanks if you know!
