Here U Are
it's one of the best yaoi manhwas for beginners as it's mostly filled with fluff and also has a really realistic approach to being gay in the society today.

I’ll rec some colored ones as you are new and they are easier to read at the beginning ^ ^
This is a REALLY hilarious read with short chapters (so no worries about the number of chapters lol), I started with this its mostly like bromance so I’d rec this for a fun start https://www.mangago.zone/read-manga/19_days/
This one is long but a wholesome whole story, I personally love it a lot https://www.mangago.zone/read-manga/here_u_are/
This is more of an action historical one with more of a plot but again, definetely worth the read https://www.mangago.zone/read-manga/king_s_maker/
This is just 4 chapters and a fun quick read https://www.mangago.zone/read-manga/cinema_next_door/
And I love this one for the fluffiness~ https://www.mangago.zone/read-manga/heesu_in_class_2/
And here’s a general list of the ones I liked but they’re generall mangas (black and white) so you can check it later imo (▰˘◡˘▰)

You can also read Cherry Blossom After Winter ^^

Starting with the classics might set ur standards way too high so I recommend reading some really good underrated ones first like "Oh! My assistant" or "Mr. 100% perfect"

I suggest you read this one because it's realistic, has a beautiful art, and nice characters (nothing too antagonist or anything). Though it's quite slow paced but I think it's worth it and very beautiful:

This one is also very, very beautiful but it focuses on people with hearing disability instead of LGBT problems in real life:

If you are looking for something fluffy and lightweight, nothing too sad, just unicorns and marshmallows kinda thing, try these:
