Indecisive Protagonist

Protagonist of this game can't make a choice between the heroines. He is either unsure about which one he loves more or is afraid of hurting the feelings of the other.

And since in the anime world it's 'okay' to not to make a choice and make everyone wait indefinitely, this is accepted as it is. Even though this considered a character flaw it doesn't effect concerned heroines endless love towards him at all...because love is so great...

PS: You can use this tag for games that the protag makes a decision later in the story too.
