I summed up three points for you about this.

1, more and more siblings fall in love because the divorce rate in China is getting higher and higher.

When parents divorce, boys may lack maternal love and sense of security, so they hope to find a girl older than themselves, because older girls are more mature, can take care of themselves and find a sense of security.

There is more and more love between brothers and sisters, probably because the age gap is not very big and there are not many obstacles in communication. The most important thing is that they can talk about everything and help each other overcome problems in life, including various problems at work.

There are many reasons why there is more and more love between brothers and sisters. No matter what the reason, as long as both sides have feelings, they will love each other for a long time before they decide to embark on the marriage hall. As family and friends, we should give this couple a blessing.

Generally speaking, it may be that men mature late, finding a girlfriend older than themselves may not be so tired, and relatively speaking, it is the most important thing for two people to fall in love.
