What if my cousin falls in love with me?

Refuse, consanguineous marriage is forbidden, otherwise the baby born is a fool. If you like your cousin's good, then you are the first fool in the world. I think your cousin must have psychological problems, because such girls often have psychological obstacles. It may be your casual behavior, which is a great happiness for her. This may be the legendary ignorance, or it may just be a temporary attraction to you.
