1, mutual respect. Couples should respect each other. Each of us will have some little secrets in our hearts. Even two people who are very close can't tell each other all the secrets.

2, more communication, more consideration for each other. Couples should think more about each other. During my college years, everyone didn't have much pressure in life, and they didn't need to shoulder the heavy responsibility of supporting their families, and they didn't know much about the taste of rice, oil and salt.

3. Keep your promise

4. Spend more time with each other. Couples must spend more time together. If it is a long-distance relationship, they should try to meet once a month, because companionship is very important.
