It's said that Acrab guys are constant in love, but in fact they can't assure that they only date one person at one time. They have many dates and they will only be loyal until they find the right one. But a Gemini guy isn't like this unless he is making fun of you otherwise you are the only one to him. Gemini guys are always faithful and loyal to love after finding ture love. They exert greatest restraint on themselves that they don't permit any mistakes, and thus they appear neurotic every day.

都说天蝎专一，其实他们做不到那种一段时间只和一个人交往，他有很多对象，一直到找到他要找的人才会专一，双子不会的，除非他跟你开玩笑，不然每一个都是唯一的，双子找到真爱后一样是专一不变的，甚至刻意克制自己不能有一丝的差错，整天弄的神经息息的。
