Tipping off the train in Karakura once more after all these years seemed like strolling back right into a past I prefer to fail to remember. The exact same roads, the exact same air filtering the aroma of the river, and the prompt, natural reminder of who I would certainly constantly been here: Keigo, the man that was an absolute, obvious loser to every single woman he ever before tried to speak with. It stung equally as a lot currently as it did back after that. My grand strategy? Move back in with my moms and dads momentarily and discover any type of task while I figured things out. But Ichigo, bless his perpetually bad-tempered spirit, urged I collapse at his place rather, claimed it was much less hassle while I took a look around. Ichigo. The man that easily had women orbiting him like some kind of popular-magnet, also when we were kids. Obviously, he's wed now.
