Do I have to leave for three months after I get a Finnish visa?

I have to go. According to the regulations of the Finnish Visa Center, the maximum stay time after visa application can't exceed three months, and the number of stay days that the embassy may issue is different according to the materials submitted by the applicant. Usually, the embassy will decide the specific validity period and stay time of the tourist visa according to the travel itinerary, air ticket reservation and accommodation order submitted and the number of insurance days purchased, that is, how long the tourist visa can stay is not fixed.
