I'd say Yu Yan.. as all the ones listed on this page are basically little kids to the mc..
When you become immortal age becomes a number, the only issue will be if the person brought up the said lover from his childhood.

Honestly, 2 or 3. If he travels in the future by an artifact, it's fine. But looking at his age, it would be weird if it's just time passing.
If theres the way I wold put my vote in Yu Yan, without beating an eye.
how about mythology phanteon which he summoned from another universe?
