The third episode of the Sakura Taisen V OVA has plenty of CMOH between Subaru and Shinjiro.
One that especially stood out to this troper was right after the fight scene between Subaru and the mysterious man from the first two episodes (as well as this one) on top of the construction site. During the fight, Subaru gets knocked out in an explosion, falls and is caught by Shinjiro. Though it's not shown on screen, it can be deduced since Subaru wakes up in Shinjiro's arms and immediately starts reprimanding him, saying "What are you doing, Taiga? What are we to do if anything happens to the lead actress? More importantly, why are you doing something so reckless?". Shinjiro's only response is "Subaru-san. Thank goodness, you're alright." Subaru goes completely silent and just rubs his back in an attempt to console him.
Made even better by the fact that you can hear the panic in Subaru's voice when they're scolding Shinjiro. Even though Shinjiro is the only one who blatantly states it, you can tell that the two of them are just relieved that the other one is safe.
Not to mention that Subaru was fighting to get the mysterious man off of Shinjiro's case in the first place.
Including by claiming that Shinjiro is Subaru's fiance.
From the same episode:
Subaru: Your straightforwardness is shocking, but it always seems to captivate the heart of the audience. (expression softens) I understand, Taiga Shinjiro. Just stay the way you are.
