I Hear the Sunspot: Theory of Happiness

This is the second volume of the I Hear the Sunspot manga series.

Synopsis
After sharing a kiss Taichi and Kōhei end up on non-speaking terms. Things get worse when a girl named Maya Ōkami enters the picture.

Taichi keeps trying to find ways to apologize to Kōhei for being drunk, but Maya keeps interfering. Moreover, she starts to despise Taichi and does everything she can to block him from Kōhei.

Eventually, Taichi apologizes to Kōhei. But their relationship is put to the test when Taichi gets a job offer from a young man named Sai. Sai owns a company called Sign, where he helps people with hearing difficulties learn sign language. Sai offers Taichi a job. But that means that Taichi must drop out of college to pursue this unique opportunity.

When Taichi tells Kōhei his plans, it devastates Kōhei, but he buries feelings deep down to make Taichi happy.

Six months later, Taichi and Kōhei haven’t spoken to each other. Kōhei gets a devastating phone call from Tomonori Yokoyama that completely buries any hope about making up with Taichi. Even so, Taichi ends up running into Kōhei when he’s asked to run an errand.
