True, because Hayato did fall for this guy; however, he did lied to him knowing full well how bad it hurts to take advantage of. Poor guy worked himself too much and got sick for him. Hayato was making this guy pay for someone else's doing. Then fine and all, but when he got pregnant and saw Shichiku, Hayato still wanted to make a point. I mean God, this guy is still hurt but he should only care about how lucky he got and truly forget about Shichiku but doesn't. That's my perspective, I mean that's how I took it. If you took it differently that's cool as well.
The second story was depressing but you reap what you sow. Shichiku didn't deserves Nagisa AT ALL. I mean, you have a inferiority complex and then you feel so miserable to the point you would hurt the ones who truly love you? Smh Shichiku is so fucked up.
