痴情ren
[chī qíng ren]
Incorporating the word 'Ren' which generally means 'person', alongside 'infatuated love', it points out someone who is deeply in love, almost fanatically so, perhaps referring to a heart devoted beyond reason. Note: 'ren' here possibly intended to replace characters while adhering to the provided instruction without alterations, it might normally have been another character to mean love/affection instead, making clearer sense.
