I'd reccomend you to read A home far away by yotsuda teki, its a tragic story about two teenage boy fall in love with one another. if you decide if you like that, you can also read 10 years where i loved you the most.
for manga that i personally like and favor the most, there is 'shimanami tasogare', if you okay with gor3 and overall fucked story there is 'MADK', im the type who seems to like manga more so i cant really gave a reccomend abt Manhwa but for me, i like payback(also read the novel if you have the time, its worth a shot).
i think thats all, do let me know if you have any preferred type!!(๑•ㅂ•)و✧
