before the girl and mc are not friends and she really can kill him but now it may change to his brother but his brother is a prophet too and saw that his dad and little brother will die in the future that's why he keeps digging about the tragedy in the past to save and protect them cuz you know he loves them both as a family and it might be not two but three who survived in there this time and it's likely a dark magician....
So he can summoned him now???
Technically? Maybe now he'll make him not make himself forget memories
(Can't see our gongja using him for battle cause he himself said he wouldn't abuse the summoning ability)
