Can you describe the wound and/or submit a picture?
Small superficial scratches may heal in a few days, others are more serious and require attention from a certified avian veterinarian. Always a risk of infection and damage to the underlying area. If there is any doubt, better to seek a vet!
Probably best to temporarily remove the wounded bird from the rest. Some species may become vicious and further attack. Is this bird eating, drinking, perching, and eliminating (going to the bathroom) normally?
I am not familiar with lovebirds, so others with experience can give better advice!

It's not her partner. Actually it's just a week when we started to keep a lovebirds, so i don't really know how to do with it. We have 2 coupled lovebirds. It happened when we woke up this morning and my brother saw that the 4 birds are together already, the smaller female one is the one who is hurt, attacked by the bigger one.

Apply gentle pressure to small cuts with a piece of gauze to stop bleeding. Be careful not to hold the bird tightly by the chest or compress his chest as this can cut off air supply.
After the bleeding has stopped, clean the wound with warm, clean water.
Apply betadine or hydrogen peroxide to the area. Be calm and soothe your bird while doing so.
