Wearing an orange Department of Corrections shirt, Jonathan Ross Pangelinan appeared in the Superior Court of Guam on Thursday for a restitution hearing.
Pangelinan was convicted and sentenced to 10 years in prison with three years suspended for the 2018 killing of co-worker Leebrick Manglona.
His prison sentence started April 23.
Manglona's family seeks more than $17,000 in funeral, rosary and power costs as restitution from Pangelinan.
Pangelinan, during last month's hearing, agreed to pay about $500 in power utility costs and about $8,700 for funeral expenses, but objected to $8,000 charged for 16 days of rosaries.
On Thursday, prosecuting attorney Jeremy Kemper requested 30 days to go over Pangelinan's opposition.
"I just want it to be over," said Eleanor Manglona San Nicolas, Leebrick Manglona's aunt.
Pangelinan initially faced murder and aggravated assault charges. He and Manglona were at a company party at Atkins Kroll on March 23, 2018, when they got into a verbal argument that escalated into a physical altercation. Pangelinan kicked Manglona twice in the upper torso and then punched him, causing him to fall to the ground.
He said he had more than eight drinks that night.
His plea agreement states he admitted to recklessly causing Manglona's death, but that he didn't intend to kill him.
Pangelinan is scheduled to return to court for a further proceedings hearing on July 18.
