http://www.mangago.me/read-manga/tell_me_the_price_of_love/ Technically the seme you want isnt the main character but its similar, uke kinda confessed to his senior but got no answer/ignored and a few years later. Seme meets the uke and wants him, kinda forced him too yeah but the main seme is a lil diff
Thank you so much(▰˘◡˘▰)
