Seiji noticed during dinner that Shika's condition seemed to be rather strange and that she kept avoiding his eyes.
'Is it because she's feeling too embarrassed about secretly looking at my ero books, or… is she finding it difficult to look at me after knowing that I look at such things?' Seiji wondered to himself.
This was a question that Seiji had been doing his best to avoid thinking about—just what his adopted sister would think of him after looking through his ero books.
Although he wasn't into anything too outrageous, having such a large sack of ero books was bad enough already!
The most common genre among his ero books was harem, which definitely exposed his true preferences. The worst would be the sis-con books… he was unable to imagine what Shika would think of those after seeing them.
