I forgot the name of this yaoi manga where the first story is a typical teacher and student relationship where the seme is the teacher and the uke is the student (let's call him "uke student") and they fell in love and stuff. The second story (the story that i actually like) is about the uke student's friend (let's call him "friend") and other classmate (let's call him "classmate"). Apparently, the friend is actually in love with the uke student and knows that he is together with the teacher. I remember one scene where the friend is heartbroken seeing the uke student and the teacher hanging out at school. The classmate (who is a slut and sleeps with both guys and girls) saw that the friend is sad and "comforts" him (the friend is the seme and the other is uke). Eventually they kind of fell in love with each other. I also remember a scene where the friend caught a flu and told the classmate to not have sex in fear of passing it to him. But the classmate kind of forced himself to him and had some sweet sex.
Please help me to find this manga. I had been finding it for a few hours and still couldn't find it.
