When I started spending Sundays with Shuu, I usually picked the Cinema as destination, making MC to wear casual clothes. The steps I did to get heart eyes result was to buy him a drink, then use the remaining turns touching Shuu (wether hair, mouth or shoulders/arms)... If done correctly, after the very last turn, he should get heart eyes and ending the date.... Of course if you pick a more pricy location (or a location that Shuu likes), that gives you more turns, and you will get it more easily too. Its up to your economy...
