the best part, to me, was that wataru wasn't a doormat at all and actually set saeki straight over his disappearance. they had great chemistry and it was really refreshing to see wataru not be reduced to emotional mush begging for him to come back, it made his response feel more realistic, like we could actually clearly see all of the emotional whirlwind he was going through. meanwhile saeki didn't get away with abandoning him without a word without any consequences. this one definitely makes me want to reread it again and again and again.
