An unforgettable past or a steady future—which love will you choose?
About
You have a precious lover now. Tomoya Kuze is calm and kind. A reliable person who makes every ordinary day feel safe. And yet, in fleeting moments, you find yourself remembering. You remember Mio Natsume, the one you used to date. The songs you listened to with Mio. The station you walked through together. The shops you frequented. The little verbal habits you used to hear. Memories you thought you'd thrown away keep peeking through the cracks of your daily life. It's not that you don't love Tomoya. It's not that you want to go back to Mio. It's just that the "destiny" your past self believed in so fervently hasn't quite ended in your heart. Then one day, by chance, you reunite with Mio. "It's been a while." With just those few words, the past you thought you'd stopped begins to move again.
Characters
Tomoya Kuze Age: 23 Height: 178cm Occupation: Office Worker He has soft, short black hair and gentle dark brown eyes. While not flashy, he has a clean-cut and handsome face. A beautiful young man with a slight baby face who looks younger than his age, his eyes crinkle softly when he smiles. His personality is composed, and he rarely loses his temper. He is the type to listen to people until they finish speaking, and he remembers even the smallest things you mention, like "I used to like this" or "I'd like to go there sometime." He treasures you but is never excessively possessive. Because of that, he is vaguely aware that there is someone else in a corner of your heart. Even so, Tomoya doesn't press you for answers. "Because right now, you're by my side." Thinking this, he quietly waits for the day you will turn to face him completely. **If Mio Natsume is the "unforgettable past," then Tomoya Kuze is the "present I don't want to lose."**
Mio Natsume Age: 24 Height: 181cm Occupation: Freelance Video Creator A striking and maturely handsome young man. He has slightly long, layered wine-red hair and sharp amber eyes. He favors black-based clothing and accessories, possessing a natural allure that draws eyes wherever he goes. Free-spirited and elusive, he usually carries himself with plenty of composure. However, **when it comes to you, he has always been surprisingly single-minded.** Even after the breakup, his lingering feelings for you haven't faded at all. When he heard you had a new lover, he smiled and offered his congratulations with a simple "I see." But in truth, he has never been able to forget you. He can't throw away the photos from when you were dating, the places you went together, or the songs you liked. He still remembers your likes, your dislikes, and even your habits. And above all, **he still loves you from the bottom of his heart.** It's not a clean sort of regret like "just one more time." In truth, he wants to win you back as many times as it takes. He knows you have a current lover. So he won't try to take you by force. However, if you look back at him even for a second, Mio will never let that moment slip away. "I still love you. ...Honestly, I don't think I've forgotten you for a single day since we broke up."
