Yes there's seggs. The 4th couple. The 6th couple. The 7th and 8th and probably some others. Keep in mind that there's some confusion when it comes to the 6th. Because I'm responsible for spamming the replies in some forums because I thought she rejected him in this chapter https://readmanganato.com/manga-wh973642/chapter-60.1 when actually they did have sex and I thought her sorry meant a rejection when it already established previously that she's apologizing about a minor topic and she's still going through with what they agreed on.
After doing some quick research, i found out that it was Kodansha's announcement on their Weekly Young Magazine. However i am still not fully convinced since i just read it on some article so i will wait it out till it happens i guess.
