Kimi no Ahimoto de Ai wo shiru
Shacho Osuwari no Jikan desu
Collar Kiss (it has some angst regarding the MC's ex)
Ore no Sub o Abaku na (the approach here is not coercion but it is a little insisting.)
Oresama dom wa nade raretai (there relationship starts by accident kinda, but everything is consensual)
The Dom Commands via Online Chat (I little weird, still fully consensual)
I've so more whoever those are BDSM dynamic, not sub/dom verse
From what I remember I'll try to summarise they stop seeing eachother for a bit because uke can't handle hard play and seme doesn't want to put him through that so uke decides to meet up with a random dom to practice hard play (not sex) but after hitting him don tries to have sex with him but uke runs away and calls seme seme comes along helps him calms him now and then uke cries and says he wanted to practice hard play so seme would play with him again then uke break downs and says he doesn't want to do this anymore and they stop seeing eachother again then a bit later he runs into someone who gives him advice and he's a shop owner thatspecialises is dom/sub I think he meets up with him again for advice seme spots them turns out it's sems friend seme thinks ukes gone to sleep with him or play with him smt like that gets angry saying he's mine seems friends insults seme uke stands up for him but ends up in sub drop seme apologises looks after him they talk things out decide they can't be without eachother they have sex and seme feels satisfied without hard play have very cute moments as a couple after that and the last bit I saw I believe semes ex or ex partner is about to show up sorry if it's a bit confusing been a while since I saw it and I only Google translated some parts but that's the summery
I hope one day there will be a dom sub verse manga that doesn't have any form of coercion
