[What a ridiculous question. Obviously not. What is there to be happy about, when the only person he loves was robbed of this very life? When he must play pretend like this for the sake of a future where that dear person might reap the fruits of his efforts? When he must suffer through the false niceties in the company of the very holy bastard who led his only family astray, who he's now sharing a table with, eating breakfast like nothing's wrong, or ever been wrong...]

... HiMERU loves being an idol. To continue so here and now is something to be happy for. But it did not come without a price. Even so... There is still so much HiMERU wants— no, deserves from this world, and he won't be satisfied until he obtains it all. That is why he must keep working toward his goals and executing every step perfectly.

[Did that answer the actual question? Maybe, maybe not. Nonetheless, he shoves a spoonful of yogurt and fruit into his mouth to signify he has nothing more to say on the matter.]
