<Spoiler in latter half>
Did you mean RidiBooks? If so you'd have to authenticate as an overseas adult to read their R19 material. Unfortunately, this is in e-book format. As I've found, it can only be read in the Ridibooks app. Which mean there is no built-in translator. But if you're an Android user you can use an app called Hi Dictionary and it does a fairly good job of being able to read over the image in the (RidiBooks) app. This is for the raws. But the translated part of the book only goes up to like vol. 1 or something.
<Spoiler>
But be warned the story is so messed up. It's just page after page of rape & abuse/confinement. Zhenya likes him, but in his own, twisted way.

BAD ENDING~ I'll save your time if you don't wish to read this
Spoilers ahead read at your own risk
Out of all the endings the author could have chosen, they decided on the worst one.
I'll save your time if you don't wish to read this,
The uke and seme were classmates and one day they realised each other's feelings and confessed and kissed. One other classmate saw them and spread rumor and probably a video/picture too. To avoid getting bullied by their classmates uke lies about the seme being gay and kissing him forcefully. The seme gets bullied and transfers to another school. Years later in med school uke receives a parcel which has a book inside and the writer being the seme the uke at first sees that the protagonist in the book has same name as him. The uke finishes the whole book. Suddenly wakes up inside the book. From there on uke meets a character who is his Stepmother's lover but looks like the seme from real world. At first they talk a litte and slowly they get so close that they slowly start falling for each other. Soon stepbrother bullies uke and makes him get in trouble and almost r*ped but the seme saves him. After all that sh*t of them falling in love and fighting together against the stepmother and the stepson who were after the uke's inheritance in the final chapter the stepmother and the stepson get off, butler dies, everyone in the mansion dies, seme dies and through a portal uke comes back home and later scenes show how the ORIGINAL uke and ORIGINAL seme are together dating even though they had never met in like 10 years or so. It's never been explained if the uke dreamed it in coma or if it was simply a transmigration but it can be concluded that the author was tired of this project and just wanted to end it. As much as I hate this ending the author probably has their own reasons for ending this story in such a stupid way.
