>>52141153I know you are joking but for a serious answer I think she doesn't invite Miko because she thinks Miko isn't the type that goes out much so Suisei is trying to respect her space or is scared of being rejected. Remember the "will Miko come to my house if I invite her? She doesn't go out a lot"
But also when she does invite Miko it seems nothing comes out of it... Although, recently Miko is going out more so Suisei may feel it's ok to invite her more
