I loved this so so much. The perfect combo of hurt and comfort ^^, I love how cute and wholesome and sweet they were. Also the lewdness of the last chapter was super hot **, and the fact that Saika took the initiative bc he didn't trust Yamada with taking care of prep was so funny to me. At first I didn't like that Saika approached Yamada to stop him from thinking loudly and I also didn't like that he wasn't rlly clear with his feelings at first, but I liked his character development, also, I feel like Saika would be the type of guy I would have a crush on, he's so manly hehe. I also loved how accepting Yamada was when Saika told him abt his powers, he didn't start to hate him or anything, instead he continued to interact with Saika normally. In conclusion, I loved everything except some Saika indecisive bits, so I'll give it a 9.2/10
Kimi to Ishin Denshin!
