kidding aside this manga is really leaving a good message for the kids reading it. Unlike crap like rental girlfriend where the dude's just a simp. 'You have friends, you have a legal identity, you are strong, don't cry because some hoe dumped you!" That's incredible.
Also if you think about it, the sun is rising, the guys are all beaten up, but they just won an entire company through their skills, hard work and sticking up for each other. Had tsuyoshi been a simp for his ex, this would have all fallen apart.
