Two people go to each other's school, high school or university together. This is probably the most romantic thing for two people to be together. They go to the place where the other person has lived for three or four years, and the other person will be your tour guide, telling you which building he once lived in, which building he attended classes in, what he ate in the cafeteria, and so on. Stroll around the campus and talk about the bits and pieces of the lush years to enhance mutual understanding. Maybe we can't participate in many people's campus life, but we can relive the little beauty together. It's romantic to think about it, and it's absolutely effective in enhancing feelings.
Third, travel together. Intimate travel is very romantic for lovers in love. Because travel in love is not as routine and fixed as honeymoon, there is more freedom, relatively more casual and free. In particular, choose a slower means of transportation, such as taking a green leather train or bus together, snuggling together when you are tired and sleepy, arriving at a place to set up an intimate photo in a beautiful place, looking for local specialties, and sharing and feeling the local customs together.
In short, for two people in love, even a small matter, choosing the right time and place can be very romantic and interesting, which can help warm up feelings.
