If you succeed in fending “them” off during the Night of the First Day, then you can accomplish something special at Romani Ranch during the Night of the Second Day. Soar to Milk Road, save your game, and then go west into the ranch. Head for Romani’s house, and then play the Song of Double Time to advance to the Night of the Second Day (6 p.m. on the Second Day).
Link, the Professional Escort
If you saved Romani’s cows from “them” during the Night of the First Day, then during the Night of the Second Day, you’ll find Romani’s sister, Cremia, readying a wagon full of Chateau Romani for a special delivery to Clock Town. Speak with Cremia near the barn and agree to go with her. After all, it’s dangerous to go alone.
As you travel through the ranch, Cremia fills you in on the trouble that she and her sister, Romani, are having around the farm. She also gives you a bit of insight about her friend Anju, who’s getting married soon. But Cremia’s joy for her friend is dampened by the sight of the looming moon.
When you reach Milk Road, Cremia suddenly brings her wagon to a halt. That’s funny… there’s a fence in the road! Seeing no other alternative, Cremia steers her wagon onto the nearby Gorman Track, taking a little detour. She has a funny feeling, and she tells Link to ready his bow.
Cremia’s trepidation is spot-on, as you’re soon pursued by evil thieves! (Hey, the masks those guys are wearing look awfully familiar…) Use your bow to fend off the thieves by shooting them with arrows. You have unlimited arrows, so just keep tapping 
to shoot the thieves each time they draw near.
Keep firing arrows at the thieves until you’re finally through the detour. Once you’re out of danger, Cremia thanks you with a special reward: Romani’s Mask. With this special mask, you can finally enter the Latte Milk Bar in East Clock Town when it’s open during the evenings. Most excellent!
