When Tadokoro hugs Aoyagi and Teshima after they collapse during the 1000km challenge, telling them how proud he is of them, also counts as a tearjerker.
Naruko's concern that it was their fault that Aoyagi and Teshima pulled muscles.
Everything about Tadokoro's relatiosnship with Aoyagi and Teshima could be a CMOH. In particular, Aoyagi idolizes him, basically taking Tadokoro's role in the team during his third year.
Teshima and Aoyagi being reduced to happy tears when Tadokoro takes the first sprint.
They also try helping him rejoin the race when he falls behind on the second day.
It's revealed during the second Inter High that Tadokoro passed on the Love Hime CD Onoda gave him to Aoyagi. It's a show not only of how much the song and Onoda's support meant to him, but how much he trusts in Aoyagi.
Instead of being angry or bitter over Onoda qualifying for the Inter-High when he didn't, Teshima basically becomes Onoda's biggest supporter, even giving him new shoes and pedals to help him improve.
Onoda being showered with affection by his teammates after he wins the Interhigh is sweet overall, but special mention should go to him getting an enthusiastic hug from Makishima.
It's easy to miss but, after Onoda wins, Teshima is in the lead when the rest of the team is climbing over the barriers to congratulate him.
Miki gently grasps his hand as he lays on the ground utterly exhausted, the same way she did after he won the mountain checkpoint during the first year welcome race.
After the Inter-High, Onoda wants to express his gratitude to his senpai and takes them to, of all places, Akibahara where he buys each of them a present.
It doubles as a Crowning Moment of Funny when Onoda doesn't just buy Makishima one gift but ten times the same thing. He's just so grateful to Makishima for helping him and teaching him.
The entire scene when Onoda and Tadokoro finally rejoin the rest of the team on the 2nd Day.
First, after initially being massively embarrassed by Onoda's "plan," Tadokoro is the one to suggest they sing once more even though there's no one around.
Tadokoro's inner monologue about cycling being fun and how grateful he is to Onoda.
Once the two finally catch sight of Sohoku's jerseys, Onoda excitedly turns back to Tadokoro to tell him, only to be shocked by the fact that he's crying with pure joy.
Tadokoro's emotions are partially due to the fact that, at one point, he was going to drop out of the cycling club because he couldn't improve. The idea of improving enough to compete in the Inter-High, only to drop out the second day, was initially devastating him until Onoda showed up.
Tadokoro taking over for Makishima for pulling the team on a climb. Makishima responds by affectionately nudging the sprinter in the ribs.
The whole movie technically, for giving Sohoku one last chance to ride together.
And speaking of, the team actually sings the Love Hime song together. As a kicker, Tadokoro is the one who suggests it.
Miyahara's flashbacks during Day 3 of the Interhigh. As it turns out, Manami was very sickly as a child, rarely coming to school and spending time in and out of hospitals. What changed? Miyahara brought him to a cycling course, telling him he could improve his health if he tried at a sport. The gesture clearly changed his life for the better.
Manami has frequently challenged Miyahara to race him because she's technically the only person he's never beaten. Miyahara refuses, because she knows he'd win in an instant. There's definitely an air of melancholy as she acknowledges he's entered a completely different world than hers, but she's still clearly very glad that cycling was able to improve his life this much.
