AWL-SE Marriage Help, I want the end of winter marriage proposal with Nami Options

[AlcyoneBlack]

Okay I want to go for that proposal event where if on the last day of winter you haven't seen the Nami's Problem, Muffy's Afternoon Date, Celia's Confession, nor Lumina's Fourth Heart Event (all the others are the second 4th Heart Event or the "they're your girlfriend and you have no choice but to marry them now" events) but you have Celia, Muffy, and Nami up to 4 hearts but you've only seen Nami's and Muffy's (by accident mind you) first fourth heart event. How do I make sure Nami is the one to come to my house on that day?

I don't want to lose the friendship with the others (since I worked so hard for that) but I also want to marry only Nami and I want to see the last day of winter proposal event since I haven't seen that yet.

Hmm. Well. I guess I'll stop being lazy and open my game and try it out. D: I'll be back soon, then~

EDIT: Alright. I had a look~
Just move the clock around normally with the X button. Change the off and on setting with R1. It says perfectly well which setting its on on the right and simply press start when you have the time you want. ;D
