I don't think so, he looked relieved after seeing the results in that envelop. He would of looked like pissed or shocked had they been related.
i see, I just a bit confused cause he kept it as secret from his little brother and the father as well. Thank you for your reply
No, you have it wrong. Haru's mother was pregnant with him before her met Tatsuya's dad
Actually the answer to your question is yes. He did not look 'relieved' to see the result but rather tense. Tatsuya already said that he wont let Haru go even if the are related or not. Thus, the chapter 'Secret' is about Tatsuya letting Haru believe they are just step brother instead of half brother. The father might have an illicit relationship with the mother even before tatsuya's mother died. So yes, this is incest.
Yeah.It's sad. I hope it doesnt weigh too heavy on Tatsuya.. :/
yrs he is his brother
No they're half brothers. In the last chapter it explains better. He doesn't want to tell him that they have the same father
lol I barely got a notification about this conversation. A month late! That's crazy but that's tough. It sucks that it ended up like that but I still wish them happiness.
he was the half-brother, referring to this page>>> http://www.mangago.zone/read-manga/uso_to_kiss/mf/v01/c006/7/
