From September Scanlations;

Here starts the Konya spinoff series, focusing more on Gorou and Verde! There’s plenty of Endou and Rikiya as well, but this story will spend more time telling the story of these heretofore side characters. The story takes place immediately after the last Konya chapter, so you can think of this as Chapter 20, just less focus on Endo/Rikiya and more on Gorou/Verde.

Vol. 1
Ohtaka is pissed! University baseball is not what he expected, and it’s all because of Chun, the odd little person who blithely chirps and constantly circles in his tall shadow. Everything Chun does only deepens Ohtaka’s scowl. His irritation skyrockets when Chun demands Ohtaka stay in the baseball club for his sake and steals Ohtaka’s first kiss!

When two people from Chun’s past are thrown in Ohtaka’s face, his agitation suddenly turns territorial—and he’s not sure why…

Will Ohtaka figure out this unfamiliar game that plays for keeps? Get ready for a fast pitch of romantic comedy and surprising love in Tweeting Love Birds!

Vol. 2
Chun is the prize in a game that plays for keeps. The only rule? No hanky-panky until after Chun is won!

News of the competition has traveled back to Chun’s dad, and he wants to know Ohtaka’s intentions toward his son. But Ohtaka hasn’t even told Chun how he feels!

Who will win Chun -- Shiratori or Ohtaka? The tension mounts in TWEETING LOVE BIRDS volume two!

Ueda Tomoharu is a cop manning a local koban station, and he’s quite happy with his job and relatively quiet life until he happens to run into yakuza member Gotouda Aki while chasing down an underwear thief… and is suddenly confessed to! Aki doesn’t seem bothered in the least about their star-crossed lovers status and eagerly dives into a super lovey-dovey relationship with his policeman, but Ueda’s about to find out just how dangerous it can be dating a mobster… in more ways than one.
