I recommend https://www.mangago.zone/read-manga/deep_love_ayu_no_monogatari/ (There’s multiple in the series, this is the first) though it might not exactly be what you’re looking for…he definitely loves the girl but when you read it that’s not necessarily the focus of the story. Also https://www.mangago.zone/read-manga/raise_wa_tanin_ga_ii/ - the guy is very much passionate with the MC, definitely more in a creepy-psychotic way which I’m not sure you’re really looking for, but it’s great! Finally, https://www.mangago.zone/read-manga/koi_dano_ai_dano/ - friends to lovers, guy falls first and it’s really cute, more of a comedy though
Male lead is madly in-love with with female lead to the point of crying. I really want to read a passionate romance where you can clearly tell how much he loves female lead.
I don’t mind tragedy.
I don’t care if it is a newer manga or old.
If it is incomplete I really want it to have a lot of chapters, but I really would prefer if it was completed tho :)
