In fact, Sagittarius boys are very popular with girls because they can talk, flirt and know themselves well. But being his girlfriend is too tiring.
There are several Sagittarius boys around me who are like this. They are really attentive and romantic when chasing a girl. But after catching up, you will gradually lose interest and then go back to explore the next prey. When they face the next prey, they will chase it in the same way. It will succeed every time, so there will be a lot of emotional debts.
