Need help looking for hentai manga

The female lead in this manga is a tsundere (short/small). She always argue with the male lead but likes him so she wrote a letter to confess to her. The male lead did not know that the letter was directed to him so he read it out loud in front of the class until he realized that the letter was for him. (Made the female lead cry) They had sex on the rooftop afterwards xD.

The second manga that I'm looking for is about a male lead colliding with the female lead, breaking her precious dildo (Is it called tama-chan?) She wants compensation(which is his dick) and she drew a face on his dick and had sex with him.

That's all i remember! (Im not sure if both manga are from the same author) Thank you to anyone who can help me identify this two manga ; - ;

I think your looking for these hentai manga. The first one is "True Feelings" by Makinosaka Shinichi in his Pure Girl tankobon. The second one is "Rosy Life" by Makinosaka Shinichi in his Pure Days tankobon. Hope this helps.

THANK YOU SO SO MUCH!! I have been looking for them forever! ;n; thanks again!!!
