help me pick a story to recommend!!

i wanna recommend a shounen ai story to my guy friend who has never read any bl. He recommended me a straight story, "My bias gets on the last train", and it was unexpectedly peak and the ml was super green flag so I wanna recommend something that holds up to that level ykk, but I can't decide between these stories, so I need yalls opinion, and I'll also add my thoughts on them if it helps :

• Park Hanhoo's Manager -
really interesting plot focused story but ml is...well i like him but that's cuz I'm a bl reader, and he isn't all that green flag but the plot is really peak.

• Here U Are -
I'm really leaning on recommending this cuz everything is amazing and i feel like it's perfect to recommend as first bl cuz it explores the topic of sexuality like for most bls being gay is normal but this one specifically talks about the problems and its more realistic but idk if it'll hit the same for my friend like would he find it as emotionally impactful as i did? I can't decide if i should recommend him a story that's emotional or plot focused.

• Who can define popularity -
its a happy story, really fun to read and amazing as well but i read it so long ago i can't remember much of it and i can only hope it is of the same level of peakness as the story he recommended me.

• At the end of the road -
really plot focused but the ml isnt exactly innocent green flag so I'm hesitant about this one, plus i remember a lotta ppl saying they were disappointed with the ending cuz it wasn't satisfying? idkk

• Murderer Llewellyn's enchanting dinner invitation -
absolute peakness but again im not confident if it'd hit the same as it did for me cuz it's more emotional

• The Spooky Love Tale of Gongchan Seol -
i feel like this is perfect cuz it's psychological and plot focused but it's not emotionally moving sighh

I can recommend him ongoing stories as well but I don't read that many ongoing stories plus it needs to be shounen ai as well, if you've any recs I'd appreciate them too!!
