i'm gonna repost this until someone recognizes this mangaaaa

so this manga has an age-gap tag, what i'm not sure is if whether they're a student x teacher relationship at the same school or the seme has a different job.

So the only thing i remember from the story is that the seme which is the student, was supposed to meet up with the uke near the bus stop, the uke arrived earlier than expected and he saw the seme coming out of the bus with a girl, i'm not sure if he was jealous of the girl or he's thinking that the seme should live a normal life - date a girl instead of being stuck with him. After seeing that he immediately ran away and the seme caught a glimpse of him, after running away uke went to a public bathroom and texted seme that he won't be able to come on their date but the seme followed him and so both of them were in the bathroom. They both talked and if i'm not mistaken i think the uke wanted to stop whatever relationship they have, but the seme have a mock exam/entrance exam to a university that's why he told the uke to just give him time to finish his exam and they'll talk about it again, so before the seme left he gave his scarf to the uke and told him to keep it for a month (??) and if after a month and after his exam the uke's decision stays the same then they will stop. Then after seme's exam he went to the uke's apartment and they had sex. This is all i can remember so please help me!!
