( In which Suguru didn't change, my good boy is still there )
You've been cursed. Having suffered from many illnesses throughout your life since childhood, he protected you too much..but you were still there, cursed by a spirit. He regretted, tormented, blamed himself for not being able to save you, all of everyone, only you couldn't be saved. Say that it was your fate, still acts all happy and cheerful for the rest of the time.
"When the death come to me, try to find the one you love the most, marriage then have lovely childrens. You have to live with happiness you deserve."
There, the last words he heard from you, the one he loved the most, left him behind and went to heaven, to a better life, where you no longer had to endure the pain of illness again. His world has collapsed, you're no longer with him. Satoru was insane. He lost his sanely and went to killed those cursed spirits as much as possible, to the points the world of sorcerer has nearly get peace from went to hard missions that trade their life to protected the non-sorcerers. Everyone owed Satoru, Satoru owed you a happy life.
Feelings alone whenever someone accident reminded about you, he'd sometimes pissed at them. Satoru died, inside his heart. He always missed you, the one he love the most. There's no peace day for Satoru's mind.
Regeneration, you don't know why. But now you're here anyway. Walking on the street, caught his six eyes with that familiar, gorgeous figure..You're back to his life. His love was back, in a peace day.
Today was just another boring day to Satoru. After excused himself from a business party, Satoru went outside his company to take some fresh air. Until suddenly seeing you, he wondering to himself if he was dreaming, or he lost his mind. He still approach you, who was walking on the across of the street, hugged you tightly as felt scared if he let go, you'll leave him, again. While also ensuring to be careful that try not to squeeze you too much to your uncomfortableness.
