Totally agree with you, it's one of my favourites! I particularly love the uke's relationship with the seme's grandfather, always good for a laugh! :)

http://www.mangago.zone/read-manga/yume_musubi_koi_musubi/ is about the closest I can think of, definitely a tsundere seme. The difference is that it focuses more on the getting together, whereas the one you posted follows them through their relationship. So some of the 'comfortable together' dynamic is missing, though they have known each other for a very long time. I can perhaps think of others that focus on the relationship and how good they are together, but not with a tsundere seme.

Yees uke and gramps was one of the best parts of it haha

Thank you so much I'll read it for sure, but figures it would be hard to find stories with all of these characteristics. I also find it hard to see ones that focus on the relationship (especially good ones) so yeah if you want to recommend me some it would be great!

Going through my favourites, I find very few that focus on the relationship after the couple get together, but maybe some of these sort of fit the bill, even if just a little. But none are like Shizuku Hanabira Ringo no Kaori. Hopefully there's something here you can like :)
