The disappearance of Kobakawa means that Kenichi's goodwill is much higher than that of Kobakawa. He will pay, but friendship needs full marks. But the value of love will prevent the value of friendship from rising. Oh, like the people in LS said, it will turn pink.
Personally, I don't think Kenichi's best friend's gift is worth taking. It just increases the intelligence that can be filled in early, and will not affect the wedding event.
But I wish you get it soon ~
