Others in the thread have already given some good suggestions. In particular I will add another vote for Wotakoi and Horimiya if you haven't seen them yet. Some more that I enjoyed:

• Chuunibyou demo Koi ga Shitai!: I would classify this one as more comedy than romance, but it is a pretty good mix. Focuses on a former chuunibyou (during middle school) that has a new neighbor that is a current chuunibyou (in high school) and the relationship that they form. Along the way they pick up a crew of chuuni-adjacent friends.
• Koi wa Sekai Seifuku no Ato de: This one is more comedy than romance. The basic premise is that the leader of a sentai group of heroes falls in love with one of the generals of the evil organization they are fighting against. I adore this series and it always breaks my heart that the manga didn't perform well enough to keep it going.
• Rikei ga Koi ni Ochita no de Shoumei shitemita: This one is not as strong as the others I have listed in my opinion, but if you are a connoisseur of the genre you might appreciate it. Basically, two data scientists try to mathematically prove through statistics/experiments that they are in love with one another. So, the comedy focuses on replicating a lot of tropes from the romcom genre and then collecting data about it. This one has two seasons, but I personally think the first season is a pretty good standalone season. The end of season 2 was...a choice...but it kind of ruined a lot of the good work done elsewhere in the series.

My personal recommendation of what I list below is A Day Before us. While I typically dislike shorts, it works very well with the format, and episode after episode gave me butterflies just watching it. It's extremely sweet and cute, though as far as comedy is more "cute funny romancey stuff". I'm sure you've seen/heard of most of what I have below, but just filling gaps in case you haven't.

Yeonae Haru Jeon / A Day Before Us - anidb - MAL - AniList - Personal Rating: 10/10

• Very heavy on cute romance. A series of shorts following soon-to-be-lovers as they come to realize what they have between each other. Streaming on Youtube.

Otaku ni Koi wa Muzukashii / Love is Hard for Otaku - anidb - MAL - AniList - Personal rating: 7.6/10

• Primarily comedy. An otaku tries to keep her otaku and fujoshi hobbies a secret at her new workplace, but her past catches up with her when she reunites with an old friend who shares her interests, and they discover more coworkers with similar passions.

Kimi ni Todoke / From Me to You - anidb - MAL - AniList - Personal rating: 9.2/10

• Primarily romance. Kuronuma Sawako, misunderstood because of her ghostly appearance, hopes to make friends and find romance when the popular Kazehaya Shouta starts talking to her.

Horimiya - anidb - MAL - AniList - Personal rating: 8/10

• A bit more drama, good comedy, and cute romance. Hori and Miyamura, both hiding secret lives, cross paths and unveil their true selves, leading to the possibility of something new and unexpected.

I recommend Tsurezure Children.
It's an anime where each episode has 2-3 short stories about a handful of recurring couples.
It's really cute and really funny, honestly probably my favourite romcom anime.

Does "dusk maiden of amnesia" count?
