i reccomend life in smokey blue.. its 8 volumes in japan, but here its only 5. even so, i think it's worth to read... its about two 40 year old ex coworkers that meet each other again after 8 years. there is a lot of smut tho (its censored) but the good thing about it is that its very "poetic", by that i mean that we can see the characters' thoughts during it about their feelings... the plot is definitely a slice of their lives, but it doesn't make it boring because you (should) get attached to the characters and get invested in their situation and relationship.. even the side characters are interesting and not one-dimensional.. for example, some random coworker of one of the mcs says that he has a wife but doesn't wear a ring, and the mc actually notices that!, so its very interesting and refreshing seeing the main characters be insightful!!!! plus its very realistic, WAY TOO REALISTIC.. it makes me miserable...
i also like the artstyle but it might not be for everyone.
only bad thing is that we dont get to see the ml's POV very often, and when we finally do, in volume 6, it isnt translated to english...
sorry... i wrote too much.. overall, it has very good writing in my opinion... https://www.mangago.me/read-manga/smoke_blue_no_ame_nochi_hare/

Any best slice of life BL anime
