Harenchi no Susume
This was so adorable with rivals falling in love with each other. It was fun watching them compete but not able to win because all of their targets were taken. Masatsugu seemed a bit useless, his timeline is so uneventful. I guess being rich and high-class does not require you to do much work.

WHAT IS THIS? There is no L in BL HAHAHHAHAAHAAHA! I can't see any love here and I can't tell which one is better.
Akutai wa Toiki to Mazariau
I have mixed feelings about this. Because I read the sequels, they explained why Touji acted this way but it does not make it right to force his feelings onto Natsume. Natsume also caved in after Touji persistently forced him into this relationship. It is an unique plot but I do not think this relationship is anything meaningful. Touji fell in love at first sight and Natsume definitely could not have fallen in love with Touji properly in these circumstances.
