Please Help Me Find This Manga!

[Finding Good BL]

I'm so lost. I've been searching for 3 hours but I can't find this. The closest I got was the similarity to Suehiro Machi-sensei's works. I suspect it to be Kirei na Oniisan wa Suki Desu Ka? (Do you like handsome men?) but since there's no full chapters anywhere idk if I'm right T_T. I did saw a raw here but I can't access the link. If you can help me, that would be awesome!!

It's amazing how many people know which manga it is by looking at this!
I read a lot of manga, but I don't know!

I think you probably found your answer since then but in case you haven't this is the manga "Shou Sensei no Ecchi na Himitsu" by Noda Nonda

It's the last chapter (6) and it's not about the main couple but their nephew
