"Going back to Natsuki" would essentially mean bringing Natsuki back to life. I think there's nothing Minami would wish for more than that, and he would sacrifice everything to make that wish come true. That would be so unfair towards Arata...
Speaking of impossible scenarios. I think if Minami had a chance to go back in time and return to his life with Natsuki, he would gladly do so and come up with some lame excuse like "Momose deserves someone better than me", and that makes me angry. 😤
If Arata were to lose his memory, what would he feel if he saw sensei for the first time again? And would Minami tell him that they were dating, or would he say nothing, hoping that Arata wouldn't fall in love with him and could have a "healthy relationship" with someone else?
Would he hesitate because he would genuinely want to free sensei from his burden, or because of jealousy and a desire to finally take Natsuki's place in sensei's heart?
I want AraKei to go on an adventurous date and end up spending the night in Minami's car in the middle of nowhere. Bonus points if the weather is cloudy or a little rainy.
Sometimes I think about how difficult it must've been for Arata to handle his feelings. Usually, people have someone they can tell their worries to and get support or advice from.
