If your brother marries a sister-in-law much younger than you,

To tell the truth, it depends on the feelings with my brother.

If it were me, my brother and I have a very good relationship, and I don't care at all. A family just wants everyone to be happy. If my brother and my sister-in-law are happy together, what does it matter if my sister-in-law is young? They spend the longest time together, and they will live together for life. They won't feel uncomfortable. Why do I feel sick? If your brother has the same feelings for you, he will care about your feelings and won't do anything that makes you uncomfortable. This matter won't cause you any trouble.

If the relationship between the landlord and his brother is not particularly good, his brother may hurt his sister-in-law more, and sometimes he will disregard your feelings and even ask you to let her go, and so on, which is more uncomfortable.

I think it is nothing more than these two situations. I think family members value harmony. Even if there are contradictions and awkward feelings in my heart, it doesn't matter if I think about my brother's happiness and sacrifice something for him. This is my heart:)
