help me find this bl pls

so I've read this bl manga back in 2020 or 2021 (i think) and its name was in japanese so i can't remember it. it takes place in a high school, mc is a pink haired guy and the ml is a dark haired guy. mc wasn't very healthy, if i remember correctly, and during the first chapters he was often in the school infirmary (and mc and ml meeting also takes place in the infirmary from what i remember but like i said it's been so long since I've read it so i can't say for sure). i cant remember the events of the manga that clearly cuz it had like 10 chapters while i was reading it and it was still getting updated. the last thing i remember about it is some sort of sports event happening in their school. pls help me find this manga I've been looking for it for days but i just can't find it
