Differences between manga and OVA

A point-form list of differences between the Kirepapa Manga and the OVA adaptation.
 * In the manga, Chisato tells Shunsuke that his marriage ended five years ago. In the OVAs, he never says this.
 * In the OVAs, Riju does not refer to Chisato's ex-wife as his (Riju's) mother, and simply states that Chisato has an ex-wife.
 * In the manga, Kakeru once jokingly calls Chisato his 'father-in-law' and 'Chi-papa'. In the OVAs, this has yet to occur.
 * In the manga, Shunsuke and Funaba once talk to each other, but in the OVAs, they are never shown talking to each other.
 * More females are seen in the manga than in the OVAs. In fact, absolutely no females are seen in the OVAs.
 * Chihiro, Chitose and Chidori appear much earlier in the OVAs than in the manga.
 * Ginsetsukan, Sensei and Riju's school have yet to appear in the OVAs.
 * In the OVA adaptation, after he learns that Chisato likes his alias, Saki Shunka, Shunsuke leans in very close to Chisato as he tells Chisato not to forget his (Chisato's) declaration of love for 'Saki Shunka'. However, in the manga, although Shunsuke says the exact same words, he is not shown leaning in towards Chisato.
 * In the manga, Chisato enters Shunsuke's house uninvited, and Shunsuke points out that Chisato is committing a crime (breaking and entering). However, in the OVA adaptation, Chisato finds the front door unlocked, and simply enters after announcing himself.
 * In the manga, Kanzaki once briefly mentions Shunsuke's mother. In the OVAs, he makes no mention of Shunsuke's mother.
 * In the manga, Shunsuke accuses Chisato of having deceived people for thirty years. In the OVAs, Shunsuke instead says: 'You look like this, but you're in your thirties...it's practically fraud.'
 * In the first manga chapter, Shunsuke accidentally damages the shirt Chisato is wearing. Chisato mentions that it is a designer shirt, and wants Shunsuke to have it fixed. In the OVA adaptation, Chisato says nothing about the shirt, and Shunsuke simply does the shirt up again.
 * In the manga, Shunsuke and Kakeru occasionally talk to each other, but in the OVAs, they are never shown talking to each other.
 * In the manga, Shunsuke portrays the character of Mizuki in a film adaptation of the Mizuki series. In the OVAs, this has yet to occur.
 * In the OVAs, Chisato's 'super deformed' expression consists of eyes drawn as blank, upside-down semicircles and teeth drawn as triangles. Only in the manga, he also was once drawn with devil horns.
