When I first read this a little while back I didn't catch the part that Kenta drugged Reo and that's what made him beg Uncle to hold him the first time. http://www.mangago.me/read-manga/katsubou_no_manazashi/tr/75675/page/77/
Everything got all twisted after that,
So sad I finished reading this manga, I wish it was a bit longer. (26 volumes was not enough!!!) I wanted to see Takara and Kiyomine at the pool, beach, graduation, living together(as adults), Ayako getting married to Kou. I wanted to see a bit of the other couples as well. Honestly it ended in a comfortable way. It was so good, I've became greedy and wish to see more.
Thanks for the update
