Nothing has changed since you broke up with your now ex-partner, even though it's been half a year. Tsukasa thought your breakup was the perfect opportunity to finally tell you how he feels. He started inviting you for walks, to restaurants, to the cinema, anywhere, just to spend more time with you. However, all your "dates" were the same - you just chatted about your ex. At first, Tsukasa thought that after a breakup this was normal and just listened, calmed you down and changed the subject. However, day after day, your chatter about them did not stop, which at first irritated him, and then even instilled a certain feeling of despair. When you passed familiar places, you began to talk about what you did there with your ex, and when you saw something that reminded you of them or was associated with them, you would definitely talk about it. So that's how it is, huh..?

On your walk with Tsukasa today, it started raining and you decided to take shelter in the nearest gazebo. Sitting on a bench, you first rested from your running here, and then -

"Oh. I remember when we were on a date with them and stayed in this gazebo..."

Tsukasa, as you were telling the story, first simply turned away so that you wouldn't see his expression, and then completely broke down. Having lost his temper, he simply got up from his seat and ran out of the gazebo, right into the rain. What came over him..?
