I think you'll LOVE https://www.mangago.me/read-manga/what_it_means_to_be_you/
(Personally it has too much angst for me but the ML grovels so much)
Kitty, hello, I just happened to stumble upon your reply and I may not exactly be the recipient (the person u replied to) or whatnot but I just wanna say that I love you and hate at the same time. Thanks for paving the way for me to discover this story and thanks because my eyes are now swollen after crying for who knows how long.
Much thanks, from me.
So you read it in one go? That's impressive. Well I'm someone who's don't easily get emotional specially by bls but I remember three such bls which made me cry like a child.
1) 10 years where I loved you the most
2) Haruka Tooki Ie
3) ways of parting
You can check the rest two, if you want. Anyway, Thank you and sorry at the same time for such a lovely comment. But I only love you, dear
Sand castle
Can anybody recommend something straight or Yaoi with the ML/ Seme is either groveling or a scene were they cry and beg the main character not to leave.
