Tigre's special luck attribute really is pretty high. Although at the same time one can only wonder if it's really luck that he got to test some high quality breasts while half or fully asleep and thus doesn't really know and remember anything about it.

Thinking about the situation analytically it actually makes sense many of the war maidens find him interesting. After all, he did genuinely gain the infatuation of one of them, and not long after he impressed a second one. It's natural the rest would start to wonder what's it all about. They are kind of similar due to their status and external circumstances. Since they possess high battle prowess, it wouldn't be strange if they all desired a strong and capable man, not some fat court noble who can only carry a ceremonial sword. Yet at the same time their social standing requires them to only look at nobles, most likely. Tigre happens to be a count of much renown and connections already, not to mention nobody can deny his worth in battle. Elen was lucky to claim him first!
