Sorry I couldn't be of much help but I hope you find it!
Ah no I have read this one tho was a good read :)
Ikr definitely one of my faves! But yeah I had a feeling it wasn't going to be the correct one but wanted to link it just in case lol
I also asked on the mangago subreddit but nothing idk if someone here will be able to help, I don’t have much info on it since I saw slides of it on TikTok. It’s a historical(?), comedy, enimes to lovers/I’m pretty sure this is what it is/ I remember the top having short blackish grayish hair and the bottom having long Brown hair he wore in that half up half down hairstyle… also I do t remember if it was an arranged marriage or something cuz they were in a relationship already… pls help I’ve been wanting to read so when I went and looked for it in my list I saw it wasn’t there ╥﹏╥
