Nice idea, romantic success chance will stay longer. And,
I've got a point.

How about if MCA adds one and only special ability to player, causes them to have more success chance at interacting to specific interaction?

• Charming / Charismatic, will have more success chance at Chatting, adds more hearts, comfort villagers along with nice words and conversations.
• Famous Comedian, will have more success chance at Joking, adds more hearts, surround villagers with laughs and great jokes.
• Meeters & Greeters, will have more success chance at Shaking Hand, adds more hearts, warm villagers' hearts with nice grips and greater handshakes.
• Greater Storytellers will have more success chance at Telling Stories, adds more hearts, grab villagers' attention with nice and interesting stories.
• Even More Flirty will have more success chance at Flirting, adds more hearts, shoot villagers' hearts with love arrows and even more flirty flirts.
• A Beloved Person, will have more success chance at Hugging, adds more hearts, warm villagers' hearts with warmer hugs.
• Best Kissers, will have more success chance at Kissing, adds more hearts, turn any villagers' hearts into ice with best and unforgotten kisses.

And the best of the better of the good ability, is:

• The World Is Here, Just For You, got when you reach a streak of one hundred golden hearts, where any ability combined into one, any accident or negative response seldomly affect to relationships, villagers will have an even more longer distance to love you, and will know you will always be there.

@TheShootingStar45 Words cannot describe how beautiful your presentation was.

Yes, but MCA need something that is powerful enough to fill what is in need in the game, like the version in 4.x, but it is upgraded and have more functions, like in 5.x. Any idea?
But if you want to discuss with me, so i'll use my special fancy words. Beware! XD
