Those who get married with a lion's mouth open, the situation later varies from person to person. Some people may be disappointed because of high expectations, leading to the breakdown of marriage, while others may successfully realize their expectations and establish a long-term marriage relationship. The following are possible scenarios:

1. Marriage stability: Some people may have successfully achieved their expectations, established a long-term marriage relationship, and performed well in marriage. These people may have clear goals and plans before marriage, and have made efforts to achieve these goals, thus realizing their expectations.

2. Broken marriage: Some people may break up their marriage because of high expectations. These people may not consider whether their expectations are realistic before marriage, or find that their expectations cannot be met after marriage, which leads to the breakdown of their marriage.

3. Problems in marriage: Some people may have problems in marriage, but they can finally overcome these problems and establish a stable marriage relationship. These people may re-examine their expectations and find solutions with their partners to establish a more stable marriage relationship.

In a word, what happens to those who talk big after marriage depends on whether their expectations are realistic, whether they can make efforts to realize these expectations and their ability to deal with problems with their partners in marriage.
