First let me address all the haters. If you are not comfortable with incest or the age difference between Haru and Ren that's fine but don't complain and troll here. Don't read it if you don't like it. However, I do respect others opinion.
Next is that all those who are getting impatient relax. There is no need for the mangaka to rush Ren and Haru to have sex as a issue is that he is underage and Haru is taking all these things into consideration. He wants Ren to know what he really is getting himself into before they go any further. They both love each other very much and I appreciate watching their characters grow first. It's not that I don't want them to have after all I am a fujoshi and that fuels me ლ(´ڡ`ლ)
In addition, omg I want to see more progress with Natsuo and Takamura sensei though. I hope he remembers him and hopefully something could start there. Hehehe
Also I am a bit suspicious of the new sensei is a bit too curious about Ren's life. Idk may be I am just overthinking it.
P.S it you made it this far thanks for reading rant.

I have an inkling that the new teacher might have been a formal rival or classmate of Haru when he was still in high school (before his encounter with Ren in Canada). That may be the reason why he is annoyingly interested in Ren's private life and Haru in general. After all, Haru could be a teacher, considering his charismatic personality and intelligence, if he did not drop out.

I agree with you. I think their age gap are not that far if I'm not wrong it's only 8 years gap imagine about age gap with Akihito and Asami (12 years). And the incest too.. Come on, since the first chapter we already know that they're not related by blood. So there's nothing wrong here. And Haru definietly still holding him self coz he knew that Ren still underage even though he doing something like that recently.
If you complaint about their kiss and do some foreplay, it wasn't a crime coz both of them want to do it.
Omg that's all I can say the yaoi gods read my mind because I wanted and was thinking about a a yaoi manga like this should come out where one gets amnesia. It all came from when I watched club Friday. There was an episode whereby one of the guys loses his memory after an accident and till this day he doesn't remember and he has moved on with other people. It was such a sad story and it's real. BL movies tear your hearts.
