Help me find a bl please

I already posted this but I can't find it so I don't think it got through but I've looking for a bl manhwa on this website its Korean and school life bl its not 18+ I think yaoi is probably the only tag and the reviews said the ending was sort of ambiguous or up to the readers to decide the cover is two guys one us blonde the other is dark hair and its the sky behind them and their leaning on a balcony it's completed and under 50 chapters I think also its not "our youth" "a shoulder to cry on" or "summertime" I've never seen it anywhere besides on this website but I have no idea how I found it and I was gonna read it but I forgot the name I just remember those few details also its not Chinese or Japanese. Lmk if anyone can help ty.
