Just read these, i can't guaranteed that those are your liking but at least you can avoid something like "I'm gonna beat you cause this girls likes you and stuff, our goddess can't be with someone like you". But for some note Wuxia and xianxia themed novels has high chance that would happen because the "common sense" in that novel is the law of juggle. Modern themed one also has it but sometimes it's because love rivals.
In my sense of literature those "beta" are "spices". It's good if add it in moderation in building conflict but it would gone bad if you add it too much, too frequent and too bland (too cliche). If you expect healthy love struggle which not involved with too much fighting and killing go and read romance themed novel, if you read Chinese novel you can expect 60% encounter those if there are "harem" and both male and female lead tag on them. Well 99% if hare tag where spotted.
