Be nice, understanding, and supportive. Go to the town at night and walk around a bit, and if you're lucky, your character will "hear a bell", then he'll "look up" and "see" Cecilia. It's all just written, which is why I used quotation marks. But anyways, if you be consistently nice, understanding, and supportive, you'll eventually raise her affection enough to where you can be a situationship! Congratumalations! Now if you'll excuse me...imma go play more games! Byyyeee, have a wonderful tiiiime~
