Konnichiwa Minna!
I've been thinking of this many times before of who will be Kenji's lover. I know that he likes Tenma but sooner or later he will face the fact that she dont like him... (*ouch that hurts* after all those times of hoping....)
So I thought that it is either Yakumo or Eri, even though he never thought that these cute and popular girls would fall for him...
So lets Decipher....
Yakumo - sweet, thoughtful, caring, silent,.....,cute! XD
Eri - energetic, helpful, shy(true feelings),....., cute and rich!
But for me I think He should be with Yakumo, because from all the time they been together working manga stuff... also shes lonely, she didnt found any man other than harima...
