Third party nowadays but loving more people in a certain time does it really happen?
It is possible to feel romantic attraction towards more than one person at the same time. This is known as being polyamorous. Some people choose to be in relationships with more than one person, with the knowledge and consent of everyone involved. Others may feel attracted to multiple people but choose to pursue only one at a time.
It is also possible to feel love and affection for multiple people at the same time, even if you are not romantically attracted to them. For example, you might have strong feelings of love for your family members, close friends, and partner(s) all at the same time. Ultimately, the capacity for love is not limited and can vary from person to person.
