Can anybody help me find this manga where the main character is a class president and he is hiding his ‘true’ personality and his love interest is a dude named sasiki? Something that starts with and S but he is a womanizer and the skips class so the teacher tells the main character to convince the womanizer to come to class and the womanizer agrees only if the class president tutors him. That is as far as I got before I accidentally closed out of the page. If anybody can help me that is much appreciated.
