Question About Bio Explosion

[Moonito]

yes!!!! Its me again! (almost every post here is mine .... ??) xD
Now... I have another question!!!
I read about bioexplosion (vanil "ultimate" skill) and it says " Homunculus self destructs and inflicts defense ignoring damage on everything within a 9x9 square around it. The damage is based on the Homunculus Maximum HP, and after the attack, its intimacy is reduced to 1."
So.... The intimacy goes to 1?!?!?!? It means that if after using that, I dont feed the homun, he will go and leave me alone ?
But... If I feed him right after using the skill.... he will be still with me (yes, with 1 intimacy)?
What do I care if it has 1 or 1k of intimacy? Whats the difference? (once he is evolved... its ok to have 1 in intimacy... isnt it?)

Hope you understand my quiestion (beacuse.... I dont speak good english and my redaction sucks too.... so you will have to figure out my question XD)

Thanks every1 for the attention (and for answering my question, no wonder how stupid they could be )
