1. Personal privacy protection: Some people think that love relationships are private and don't want to be known by the outside world.
2. Opposition from family and friends: If this relationship is opposed by family or friends, you may choose not to make it public to avoid unnecessary trouble.
3. Work or academic reasons: Some professional or academic environments may not allow open love relationships, so choose a low profile.
4. Emotional instability: Sometimes people choose not to disclose their love relationship because they are not sure whether their relationship is stable or want long-term development.
In short, everyone's situation is different. When choosing whether to start a relationship, you need to consider your own situation and feelings. The most important thing is to communicate frankly with your partner and decide whether to start a relationship together.
