-this one...just no. It has so many things wrong with it: she sleeps with a guy who dumped her, the guy she ended up with was already married and divorced because of her, etc.
She falls in love easily - fine, I'll let that go. But that doesn't mean she should try to seduce a stranger she just met the second after she "fell in love" - not to mention she fell in love within the first 10 seconds after meeting him for the first time.
The author glazes over the heroine's selfishness and tries to justify her actions as a result of a sad past. Well, regardless of a sad past or not, what she did is still wrong and inappropriate as the heroine. She is not an anti-hero. This means the author is ing her actions as right and acceptable, which I find even more repulsive.
As for that guy she fell in love with: I don't even want to mention him. He's an adult. He should know better and not be so impulsive. In any case, his actions just goes to show what kind of man he is - the kind to throw his marriage vows to his wife and his love for her out the window after meeting a high school girl 3 times. But this is not what irked me the most. What really irked me is that the author portrayed him as a nice, polite, and gentlemanly person. Such people like this jerk exists, despite their exterior, but I don't want to see him portrayed as a good person - because he's not. This is how the author portrays him: his unfaithfulness is acceptable since he seems nice, and his wife has developed a bad temper (and, of course, we are not told why the wife became like that.) Well let me ask you, is the wife's story told? NO, so the author shouldn't imply that his wife is bad in order to try to justify him as a decent husband - decent enough to betray her, that is.
Moreover, his actions are contradicting : when he first meets the teenaged girl, he scolds her for seducing him and suggesting that he should let her go to his house - to do what? Sleep with him, obviously. Watching a movie only served as an excuse. It may be true she is interested in the movie, but she can just wait for the next day when he returns it. So scolding her was right. Good job, mangaka, portraying the guy as a good guy. Then how about the 3rd time he sees her? HE LETS HER GO TO HIS HOUSE WHILE HIS WIFE IS AWAY. Only an idiot does that - that or he wants to have an affair already. Not to mention, he fell in love with the teenaged girl-who-looks-like-his-daughter too fast - so fast that I DIDN'T EVEN SEE IT COMING. Here's what happened: on that 3rd time he meets her, they go to his house. His wife just happens to come back. Obviously, she gets upset and leaves. Her husband does not chase after her because "he'll explain later." (Oh, you love her so much, don't you? A NORMAL PERSON WOULD CHASE AFTER HER!) The teenaged girl then professes her love again. Then the 30-year-old man kisses her. (WAIT. WHAT?! Wasn't this the guy who was lecturing her about propriety just a while ago ??? ) Later on, he decides to "break up" with the teenaged girl (when nothing actually started... (0_0)p ) Why? This is the explanation the narration gives us: "suddenly, he realized he loved his wife more." Oh-ho. Now ain't that shocking? (NOT. If it was the other way around, I'd be more shocked.) BUT WAIT - he divorces his wife later on to be with his teenaged daughter - whoops, I mean girlfriend. (Major face palm. But for some reason, I'm not shocked anymore...maybe because I don't expect anything better from this jerk.)
1/10. 0 if possible
TL;DR - don't read the second story. Read the first and third one. They're good. 7.9/10
