From Fantasyshrine:

3) Sweet Honey Drops
Gunkichi and Keita (the kids) are growing up and falling in love.

4) Act.
For Ryouchi it's love at first sight with actor Sou Seiji. Getting a job near his idol is the first step for Ryouchi, but of course, Seiji is not the person Ryouchi thinks he is.

5) Dandy at Dawn
Newspaper writer Tetsuya manages to implode his big city life and has to move back to the country. Waiting for him is neighborhood boy Kyosuke who's gotten much bigger in his absence.
